Acer S7 ultrabook exception in Windows 8

TheToshiba PA3817U-1BRS Batterysurprises out of the box. In the right direction also. We stopped by the progress made in terms of design and finish. This is not the first time that we note about appliances giant global computer, but it is truer than ever. Acer wants to erase its image builder input range and S7 is the embodiment of this desire.

Between the Macbook Air and otherToshiba Satellite U405 SeriesUltrabooks, we can say that we had more than our fair share of ultra-portable in recent months. S7 still managed to surprise with its design to say the least. Far rather masculine dark colors that adorn most of the production unit impresses with its blend dress white glass and aluminum. It is very pretty and has joined the editorial staff but it is possible that this bias does not appeal to everyone. At the same time, we must dare to stand out and it succeeded. We may have some doubts about the usefulness of this glass plate on the back of the screen that represents a potential weak point. From this point of view, all aluminum finish of the 11.6-inchDell Latitude E5400 Batteryvariant is preferable.

Anyway, the design is successful frankly, the S7 is extremely fine and displays the original lines. The finish is generally very high quality even if you notice a few things that deserved a little more attention. We would like to see for example the connection directly cut from aluminum rather than being surrounded by plastic. All is not perfect, but it is the best computer in the history of Acer and certainly one of the prettiest in recent years, all brands. A great performance when you think about what was on the PC market a few years ago.

With a computerDell Inspiron 1210 Batteryso thin you can not help but fear that the keyboard appears uncomfortable. If the chicklet keyboard S7 is large and well arranged, it is indeed not the most comfortable car keys lack depth and pressure resistance is minimal. This is probably due to the available space and you can not have everything. This does not prevent you from typing the same long but we saw more enjoyable, even on an ultraportable. Mention may be made or the Lenovo Yoga UX32VD Asus.

The touchpad is it efficient, accurate without being huge. It should also keep in mind that requires touchscreen, it is used much less often than the previous line of computers. Always within ergonomics, we discuss a small defect at the edges of the device. These are indeed very sharp. You will not cut you but they prove uncomfortable when you let sit on his wrists.

Like the Lenovo Yoga, theDell Precision M6400is Ultrabook "classic" which was added a touchscreen. Both products nevertheless express very different philosophies. The S7 uses a hinge limited to 180 ° opening where Yoga operates a complete reversal of the slab. Here it is possible to lower the screen on the table (for a example) but not to reverse completely. No change in use, but tablet so nice all the same because the screen is not top off fingers.

However, we gain 250 grams compared to Yoga. As we noted at the sight of the machine at IFA, the hinge also offers a very high resistance needed to use touch.

The slab itself is very satisfactory.Dell Studio 1535 BatteryUsingIPS technology and Full HD resolution, the screen offers a beautiful image. Brightness and contrast are at the rendezvous, while the colors are more accurate and slightly saturated. This is not the most accurate but it is more flattering to the eye. The only drawback is the presence of reflections induced by capacitive overlay which is inevitable. Note that the glass surface is a Gorilla Glass 2 which should ensure a very high resistance to shocks. The sound is also a pleasant surprise. Despite the fine,Dell Precision M2400 Batteryhas managed to offer a generous volume and fairly balanced.

The S7 is available in several versions, ranging from the Core i5 and Core i7 with 128 or 256 GB SSD. We appreciate the choices, the unique configuration is too often the norm. Our test model was equipped with "that" Intel Core i5 performance but were more than satisfactory with Windows 8 decidedly low resource utilization. All tasks are possible in good conditions and with the SSD as a couple, you do not wait long recording or opening program. Suffice to say that for the interface and HTML applications, it is really perfect. For heavy video editing, you can always choose the Core i7 butToshiba PA3634U-1BAS Batteryit must have utility.

With so little room for the battery, the battery life is not exceptional but remains in the standard of Ultrabook. Allow about 4:45 on a single charge and video which should take more than 5hoursin office. The S7 is unfortunately quite noisy, which is even more annoying than the fan runs almost constantly. A probable consequence of the smoothness again. However, the heat dissipation is very good, no place is too hot chassis.

Acer S7: the most attractive Ultrabook

The Acer ultrabook S7 is undoubtedly one of the most impressive notebook of this generation, if not all the time, and it is probably no coincidence that Microsoft has put forward in its promotion of Windows 8 . Acer has really done a great job on this design model. All is not perfect yet but getting close. Concerning the use touchscreen Windows 8, the S7 is clearly not the most innovative. However, theDell Studio 1555 Batteryexperience is very pleasant and we naturally use touch as soon as the opportunity presents itself. Acer uses a great slab and the hinge is designed to withstand the slides using touch. However, do not be fooled, the S7 is a notebook, a real one. However, we can not help but imagine the S7 has a solution transformation tablet hybrid ultimate form. If Acer could hear us ...

Remains the thorny issue of price. Acer if we had used previously to products in reasonable price, this is not really the case here. S7 Ultrabook is a decidedly upscale, and it pays cash, € 1,300 for the version "basic" in Core i5 and 128GB SSD This is not unreasonable given the quality of this notebookDell Studio 1558 Batterybut we will think twice. Remains as the S7 is currently no real direct competitor, only tactile versions of Asus Zenbooks or Samsung Series 9 could compete but nothing on the horizon at the moment.

iPad Retina: the change in continuity?

Since return to the launch of the highly anticipated iPad mini a few weeks ago (seeiPad Mini: Apple's tablet 7.9 inch), Apple was updating its tablet launch, the iPad, offering "the iPad with Retina display. " On the menu this update, a new faster processor announced some small adjustments annexes.

Yet the original iPad is not so old: it is starting up in March Apple marketing "new iPad", the third generation of its tablet success (see Apple iPad: the third generation test). While rumors for months evoked an iPad 3 with HD display, this is precisely what the Apple brand we proposed. A little over a half has passed since then and while the Retina display is still valid for the iPad, Apple sees its tablet features to provide a new processor twice as announced fast. Review details!

Design sommaireAprès return to the "new iPad" Apple gives us so "iPad with Retina display." We appreciate the ingenuity semantic ... For convenience, we call iPad Retina. In this update, Apple does not change the design of its 9.7-inch tablet. We thus find the aluminum frame with rounded edges to facilitate handling with dimensions identical to the "new iPad" ie, 18.5 cm wide, 24.1 cm high and 9.4 mm thick. Weight does not change with 652 grams for the Wi-Fi model and 662 grams for the Wi-Fi version + Cellular. And Apple is still the iPad in two colors: black or white.

Recall that the iPad has a Retina start button, two buttons for adjusting the volume and lock button programmable (optional orientation lock or mute). The display has naturally its center button and found a mini-jack for audio at the top of the tabletDell Inspiron 1210.

The big news here is the design ... Exit the connector 30-pin connector and place the new connector Lightning opened with the iPhone 5. Remember that this connector provides benefits only for certain miniaturization and the possibility of connecting the cable in one direction or the other. Remains a major drawback: the connector Lightning makes iPad compatible with all accessories with a dock connector traditional ... And if the name Lightning suggests high performance, Retina iPad continues to enjoy a USB 2.0 interface: it There is therefore no hope of gain transfer speeds which is directly related to the change in connectivity. Moreover, while the connector Lightning sense on compact devices like iPod particular, the smallness of the connector relative to the imposing size of the tablet here is a handicap: we are surprised to find it difficult to insert or pull the plug!

Components and return to screen OverviewDignity novelty of this iPad Retina is the processor. While the "new iPad" using the A5X, a dual-heart with a chipset boosted to ensure fluidity necessary to support the resolution Retina, iPad takes advantage of the Retina A6X. Variant of the A6 launched with the iPhone 5,inspiron 6400has two execution cores running at 1.4 GHz (1 GHz against the iPhone 5) and a graphics chip severe muscular and presented as quad Apple-core.

The graphical part of new benefits in effect with the inclusion of new SGX cores, the SGX554 PowerVR. Here Apple has doubled the number of computing units while we note a slight gain frequency: 300 MHz against 250 MHz above. Apple announces and graphics performance than twice that expected to see games appear Retina greedy but, hopefully, more realistic. In all cases, the A6X this fourth-generation iPad will be based on a 1 GB RAM and substantial little refinement: the chip A6X visibly etched 32 nm against 45 nm for the previous A5X. A detail which is important since it allows to put more computing units, we have seen, while containing essential parameters such as heat or electricity consumption. In use, the iPad Retina warms up a bit but still significantly less than its predecessor which is welcome.

Thedell inspiron 6000enjoys a circuit Wi-Fi dual-band i802.11a/b/g/n whose maximum speed can now reach 150 Mbit / s and a circuit 3G, if you opt for the model Wi -Fi + Cellular. Bluetooth is part of version 4.0. Only models and Wi-Fi + GPS Cellular advantage.

Side of the screen, Apple offers us as the previous iPad ... Retina screen. The latter boasts a definition of 2048 x 1536 pixels, or more or less 3.1 million pixels on the screen. Pixel density here is 264 pixels per inch. In practice this can obviously enjoy a fine display of more pleasant with large text and icons ... such fine and detailed. In the area there are many who do better than Google with its Nexus 10, the recent definition of 2560 x 1600 pixels achieves a resolution of 300 pixels per inch.

Remember that to take advantage of the Retina display, iPad applications should be reviewed to include Retina graphics. Since the release of "New iPad" a number of the 275,000 claimed by Apple iPad apps have already been updated. It is naturally non-optimized apps while Retina Retina said graphic that says occupation than the app in system memory.

The side of the battery, the iPad has a Retina 42.5 Wh Lithium and if Apple always communicates on a range of ten hours on Wi-Fi, the novelty of this iteration is to seek side of the charger because the charger brand book now 12 Watts instead of 10 Watts model above. Remains that the load is still very long.

Camera back to sommaireComme its predecessor, the iPad Retina acquires iSight camera of 5 megapixels with optics composed of five elements. Open at f: 2.4, it is accompanied by a system of autofocus and an infrared filter.

If the iSight does not change between the new iPad Retina and iPad, there are logically the ability to record HD video in 1080p. Remains whether the size of the iPad lends itself actually taking pictures or videos, which is another debate ...

For its part, the front camera FaceTime operates a 1.2 megapixel HD sensor capable of running 720p. This is clearly a step in front of the third-generation iPad but always confined the camera to use booster.

Unavoidable, the SunSpider test measures the speed of our shelves for Javascript. The results are expressed in milliseconds, reading the graph is reversed: the smallest bar representing the fastest tablet. The iPad Retina ends before the first VivoTab Asus RT in Windows. Progress against the previous generation iPad is here obvious.

Linpack is concerned with the rawdell xps m1210 batterypower of our processors. The test is completely synthetic and the result is a plebiscite for iPad Retina. Linpack score here is almost four times higher than the new iPad and therefore well above competing tablets.

Synthetic test, GLBenchmark for measuring the graphics performance of our shelves. The iPad Retina climbed into first place with 42% performance over the Nexus 10 and 94% higher against its predecessor, the "new iPad." It is quite close to doubling performance announced.

Conclusion return sommaireA barely six months after having marketed the "new iPad" Apple already gives offspring. Now called "iPad with Retina display", this fourth generation iPad retains the Retina display that was the whole point of his predecessor. Aesthetically and then the newest tablets Apple retains the look and feel inaugurated with the iPad 2, we need to look to understand the processor change. With A6X, Apple actually gives a nice boost to the performance of the iPad, even if for the moment the applications that can actually benefit seems limited. Nevertheless, this opens the way to more realistic games that we always wait to try it!

Faster with the new connection Lightning, iPad Retina also benefits from a front camera FaceTime HD improved ... updates frankly welcome to a new buyer but not sufficient for those who last March broke the piggy bank to s offer a third-generation iPad. Especially since we do not really know if a new new iPad with Retina display still would not be on the side of Cupertino preparation for release in the spring with a new chassis why not similar to the iPad Mini!

Ultimately iPad Retina is a very good tablet, with the now well-known limitations of the Environment Apple (iTunes / iCloud as keystone HDMI / USB optional inability to expand theInspiron Mini 12 Batterystorage capacity, etc.) but also, and this is a fact, the software environment tablet's richest moment. Apple claims not far from 275,000 applications for the iPad. Yet if the iPad wins for the moment hands down in terms of the repository, its price remains high. Opposite, the competition is organized and becomes more credible. It is believed by the Google Nexus 10 (see Nexus 10: Google tablet by Samsung) which, if it can not compete in terms of finish, made a strong impression on the technical and price for a fairly aggressive. Damage however it is so difficult to get one.

Microsoft Surface: Living test with Windows RT

Concurrent with the launch of Windows 8, the software giant has unveiled Surface, its new and first tablet equipped with Windows RT. If the editor was a pioneer in the field of tabletsDell Studio 1555with the Tablet PC Edition of Windows XP, it should be recognized that the concept of tablet has really taken off with the advent of the Apple iPad ... 2010. And while the early 2000s Microsoft laid the foundations of a touch interface, the company had accumulated a delay in the matter whatsoever with Windows Vista or Windows 7. A delay that has at least presided over the design of the latest version of Windows and more specifically its multi-touch interfaceModern UI(formerly called Metro).

With Surface, Microsoft embarked on the battle of what Steve Jobs described the Post PC era. Usually if Microsoft simply provide the software, leaving it to its partners to develop hardware solutions operator, brand Steve Ballmer takes a turn with significant size. For the first time in its history Microsoft actually sells a computer, specifically a tablet equipped with Windows and under its own brand. In the history of the company is not trivial. There are certainly precedents with the Xbox, but also very bad memories with Zune and Kin to name a few.

In his presentation to the press last summer, Surface was impressed. Beyond the shift driven by Steve Ballmer, now Microsoft speaks as a company "Devices + Services" area brings the world of tablet some new concepts to the less interesting. One thinks of course or integrated support for ingenious keyboard that we longed to try. Place therefore testing with Windows Surface RT!

Two versions of Surface

Before we look at the design of this area, we must clarify that Microsoft will be releasing two different versions of the tablet. The first, which we are discussing today, is named Windows Surface RT. It is a tablet with ARM processor Windows embarking RT. And who says Windows RT, says no compatibility with all Windows x86 applications developed to date.

By the end of the year, Microsoft will offer a variant of Intel's tablet surface. This latest version will be equipped with a x86 processor and will run Windows 8 on this area it will be possible to run Photoshop and play the Sims 3, for example.

Why two different size? Hard to say, Microsoft clearly needed a tablet ARM to provide a device light, compact, fanless and with autonomy capable of running Windows RT, the first ARM version of Windows. The question remains, whether the concessions made by Microsoft to achieve this will be accepted.

Surface design

Comes in a neat and minimalist packaging that evokes necessarily the best packaging of the Apple brand, the tablet space with Windows RT innovates not necessarily the attributes of design. Outwardly it resembles many other tablets we've seen so far. Provided do not think it is yet another tablet ... with the big area of ​​innovation focuses on some details, it is true feel good.

Externally, theDell Vostro 1710uses a frame in dark tones made of a magnesium alloy, that called VaporMG Microsoft, one of which properties would be three lighter than aluminum. Found on the left side a + / - buttons for volume, a mini-jack, while the right side houses a USB 2.0 port, micro-HDMI connector and plug. The latter is magnetized as Macbook MagSafe connector (we will pay attention to its implementation because the slope with the edge of the shell surface can believe that the adapter is connected when it is not Fortunately, one white LED turns on when charging connector). The start button is located on top of the camera while the Windows button below the screen is touch sensitive, a very good choice which avoids pressure sometimes risky as the Samsung Slate example.

Front, Surface has a 720p HD camera, like the back of the unit where a second camera HD 720p is present. Here we regret the lack of real quality digital camera ... When competing tablets offer the 5 megapixel, megapixel size seems feeble. In terms of audio, the tablet has two microphones and speakers.

Is that all? Not quite! The lower part of the back of the unit unfolds to become a kind of foot is what Microsoft calls the "kickstand". In this way, and without any other accessory, the tablet can stand upright, always in landscape mode, as a single non-adjustable angle. The mechanism of this integrated foot appears relatively robust.

Once opened, the "kickstand" reveals the very well hidden SDXC memory card reader. Finally at the bottom of the screen there are a proprietary connector that will be used for keyboard surface.

On balance, size, excluding accessories, claims a weight of 680 grams: it is a few ounces more than aniPad mini.

Living in the heart of Windows with RT

Technical side, this area is driven by a quad-core processor NVIDIA Tegra 3 32 bits that we know pretty well now. The latter is clocked at 1.3 GHz and is seen with 2 GB of RAM.

Regarding storage, Microsoft Surface declines in two versions: 32 or 64 GB And much talk now that angry. Our tablet 32GB, only 14 GB are free on a total of 24.9 GB as seen by the operating system. Here we can only regret the lack of transparency Microsoft: the system and its apps occupy the place is one thing, but the advertised 32GB is not usable, far from it, is not acceptable.

There are of course the support of Wi-Fi i802.11 a / b / g / n and Bluetooth version 4.0 here with support for Bluetooth profiles including A2DP stereo audio. Surface and has various sensors with an accelerometer and a gyroscope and an ambient light sensor.

The thorny case of photo sensors

In terms of photo, benefits are average size, including a positioning problem which requires the sensor to tilt back a little shelf on one side for a photo that is level.

Surface sensors but also suffer quite dramatically and the phenomenon of "hot pixels" in dark environments. It manifests itself in the presence of pixel color (white, red, green, etc), in the case of the surface, which appear fixed location on the screen but on the final picture. How do you explain that? The photo sensors are composed of pixels that occur for each photon received a corresponding electrical charge. These charges are then sampled and quantized to be converted into a digital signal. TheDell Vostro 1720 Batteryproblem is that the leakage current in the boost sensor are sometimes some pixels, which will then appear brighter than in reality or completely white (or red, green or blue depending on the location of the pixel under Bayer matrix). This problem is accentuated when the sensor heats up, since leakage currents are sensitive to temperature. And the sensor is hot when mounted in ISO (or a longer exposure is carried out), with which amplifies the electric current. Conversely, it disappears when you take a picture in a bright environment, since the ISO and the sensor cools down. This problem is long hot pixels, but manufacturers usually know their map sensors to correct the problem ...

The audio is an earful!

By plugging a headset on the surface, volume set unintentionally thoroughly, we literally jumped! Audio output does not seem the same rules clamping power than other mobile devices that are passed to the drafting date. We decided to apply the same test protocol as for portable audio. Surface then reaches an impressive 104.7 dB 99.3 dB against the iPad 3. For the record, the player with the highest score in this test is the Cowon i10 with 101.5 dB. 3.2 dB more for the area facing the Cowon, so dubbed sound power in logarithmic scale!

Keyboards Surface: Touch and Type Cover Cover

To differentiate its tablet from the plethora of other already available on the market, but also anchor it in a way of creating content, Microsoft has developed a system keyboard "dockable" to surface. Sold separately, these keyboards are available in various colors and offer two completely different sensations.

Thus Touch Cover, also available as a bundle with space, proposes a membrane keypad. Simply touch the various buttons (78 at last count) for your entry appears on the screen. Since no mechanical feedback lets you feel not so striking has been taken into account with this keyboard, Microsoft accompanies each keystroke with a slight sound from the tablet, like the keyboard touch. Please note a series of dedicated keys to RT with Windows volume control, direct access to Windows icons (search, share, set, etc) ... The keyboard is completed with a touchpad to move the mouse pointer on the desktop. Here the click buttons are located on the edge of the keyboard and it is not very practical.

The other sensation offered by Microsoft is more traditional. Type the Cover offers indeed a mechanical keypad. There are still 78 keys here and those dedicated to Windows RT benefit marking function keys (F1, F2, etc.). As he enjoys the touchpad two buttons and clickable truly is quite significant. Disadvantage: this keyboard is thicker.

In both cases,Dell Studio 1536keyboards Surface weigh around 200 grams, require no battery or specific pairing and connect easily to the tablet via their magnetic connector. The action of docking emits a characteristic sound which was highlighted by the first ads for Surface. Since the keyboard is set to be closed on the tablet screen (and yes it turns the screen size), it has serious reservations Type Cover for mechanical keys which are in direct contact with the screen with the risk of scratching. No worries on the side of Touch Cover and its soft keys. Remains closed once on the screen, the back of the keyboard has a particular look, a kind of felt that qualify any carpet or upholstery of car interior. This is ... strange.

A word about the use of these keyboards. One that intrigued us the most is obviously the Touch Cover. The lack of typing feel it provides is a curiosity that leads to instinctively rely heavily on the keys. Or do not. The touch is enough and gives much better results. It takes time to adapt to begin to take advantage of Touch Cover, and ensure that all entered letters actually appear on the screen. The touch area for the mouse, however, is more difficult to handle especially because of the sensitive buttons located on the edge of the keyboard. And we note that the use of the black keys Touch Cover, including the area of ​​the mice tend to whiten.

Cover Type the keyboard is certainly the most compelling even though we would have preferred a wider Touchpad for the mouse.

RT Windows: a closed environment

Alongside the development of Windows 8, Microsoft has developed Windows RT. It is neither more nor less than a port for the ARM architecture of Windows 8. We find the same functionality as a result, at least in outline, as well as Windows 8 Modern UI touch interface, the screen welcomes us start with the first start of the tablet.

Who says ARM version of Windows, we mean a compromise. The first and not the least is the total incompatibility of all your software with Windows RT. Useless to try to run your software on x86 Windows Surface RT: they will not work.

The only way to get Windows software with RT is through the Windows Store. Indeed, although the classic desktop is still present in this version of Windows, the only channel supported for installing applications is the Microsoft Marketplace. A Windows Store, the content remains as we speak rather meager. Worse, Microsoft itself does not play the game totally since many of its titles developed specifically for Windows 8 as packs or Microsoft Games Mahjong Solitaire Collection are not available for Windows RT at the time we publish these lines. And besides, do not try to play a DVD with Windows RT: software likeVostro 1088 BatteryPowerDVD Mobile yet available on Windows Store is not compatible with Windows RT.

But back to the desktop. We told you, the Windows desktop is now at the heart of Windows RT, and is accessible from the tile on the start screen like Windows 8. Yes but now, here's office is useless ... or almost: there are only the standard Windows application (Paint, Notepad, etc.)., The classic version of Internet Explorer as well as management tools and Windows file management that we know well. Applications Office Home and Student 2013 RT delivered with the OS also run on the desktop. But that's all. Indeed, third-party developers will not have the opportunity to develop software for the Windows desktop RT.

An ecosystem with little apps

Take a stupid case: connecting the camera area and pass on the desktopStudio 1440to recover photos via copy / paste. We want the view: photos open one after the other in the Modern UI environment that only allows the display (the rest crispantes with delays). To edit them, we say we're going to install Photoshop or Paint Shop Pro or Lightroom or even a basic Xnview ... Before reconsider all these apps are conspicuously absent on Windows RT.

We repeated the same observation with IM conversations. RT Windows, like Windows 8, which offers the Messages application automatically connects you to your networks. Conversations take place between your contacts so but in full screen mode and without the ability to send or receive files. We said we will have to install Windows Live Essentials 2012 to receive a Messenger with file exchanges and conversations tab ... before there yet disillusioned.

If by chance you want to use the tablet for watching movies and any random MKV, no luck! RT Windows does not support this file format, and there is currently no solution except to third-party application or convert video files. MOV and MP4 formats, however, are natively supported. Remains to be seen what conditions since according to their format videos and we could see stuttering or slowness in some readings, including 1080p.

Also mention the lack of built-in firewall, although Windows Defender is part of, or the inability to take control of space through a standard remote desktop. Note however that the area offers good Remote Desktop app for control from your tablet PC on your network. Good point, the "history file" inherited from Windows 8 can be used with a memory card into the SD-XC.

For applications offered by the WinRT Windows Store is not glorious. If Skype is available for Windows RT, some games available in Microsoft Windows 8 is here simply absent then an application like Shazam who just see the Update for Windows 8 is not available in ARM ...

Sure, Windows RT comes with the Office suite. At least Home and Student version, ie without Outlook or Publisher. We therefore just full versions of Word, Excel, Powerpoint and Onenote running for office. It is true that here Microsoft scores one point, no competitor environment whether iOS or Android do not offer desktop applications that can even compete with that Word or Excel. Note that the first copies of Windows for Surface RT come with a version of "Preview" of Office 2013 that is automatically updated to the final version from Windows Update.

Ultimately, if using Windows Surface RT is definitely an experience, the familiarity of the Windows environment on a touch pad with something reassuring, this familiarity is ultimately an illusion: RT Windows does that very limited compatibility with traditional Windows ecosystem.

RT Windows: Devices

The other concession that Windows is at RT devices: if Microsoft has developed a set of drivers ARM, do not expect to be able to use your device the most "exotic" with your area. And sometimes exotic is not necessarily where you think.

Small inventory: naturally the most obviousInspiron 1750devices such as keyboard / mouse USB key / USB drives are supported. The rest on this, RT Windows can read and write to NTFS without media attention. USB audio devices as our standard USB Headset Logitech Clearchat are also supported. However our Lumia 800, it is well known, is unusable due to lack of application (application synchronization of Windows Phone Windows Store seems reserved for Windows Phone . IPod Touch is well known for its party access to storage and therefore the photos but iTunes music you can do anything with it. Our TV tuner Pinnacle is unsurprisingly unusable fault driver. The Microsoft Zune Flash is not longer recognized by Surface, as our Microsoft Lifecam Studio webcam or Logitech G920 ... Our Epson is well recognized but the driver is not found rendering it unusable and so on.

However, we appreciate the good support USB hubs or the cameras: photos of our D300 and HX9V are accessible without worry. A final word on printers: Photosmart C310 our HP was recognized by Windows RT and we were able to print without any problem.

Surface: Some software benefits

In addition to the Office suite, we can mention another advantage for Microsoft: managing user accounts. This feature is absent from iOS and Android (except third-party application) and actually present in the heart of Windows RT. This allows the tablet to pass quietly spouse or children by ensuring they have their apps and settings without interfering with yours.

This is not the only positive for Microsoft, anyway. RT Windows Internet Explorer loads in two versions: Classic and Modern UI on the desktop. We thus find the browser capabilities but also led support Flash technology. Microsoft has effectively integrated Flash engine at the heart of Internet Explorer even in Windows RT this version, at least on the version of Metro / Modern UI. Remains only the sites that have been whitelistés Microsoft can view Flash content: they are now few.

Living with Windows RT: hardware

Regarding the tabletdell xps m1710, it is frankly good quality, despite finishing a little rough in places. On our test there are days between the frame and the upper part of the screen while the button start seems a bit feeble and we do not always know if the contact is effective. We regret too geometric design that makes its grip sometimes uncomfortable, just as with the first iPad. And while the landscape orientation is perfect for the Modern UI environment, we discover serious limitations when switching to portrait mode. The office already frankly very usable in touch here becomes the object of ridicule and the start screen if it operates a rearrangement of its tiles shows that it was primarily designed for landscape mode (blank screen under certain tiles, themes to customize the Start screen garbled, etc). In addition, the Windows touch button can be found under your left hand and can then be activated inadvertently.

And how once again overlook incompatibilities with certain applications? Software design proposed Fresh Paint on the Windows Store is not compatible with portrait mode, just as Skype, developed two applications - remember the - Microsoft! And these are not isolated cases unfortunately. Example with Larousse dictionary which also runs only in landscape mode ...

Living with Windows RT: its slowness, its bugs

Unfortunately, Surface surprises do not stop there. Thus we see after a few uses the fluidity and speed observed on Windows 8 tablets are not appropriate here. There noticeable delays when certain actions if one of the first update size is back on this, especially to offer a Modern UI screen actually fluid, is annoyed by the slow shift when we tilt the tablet. Startup complete it can sometimes be quite long but fortunately, in normal use, surface is mostly idle except for ... crash. The start of Metro apps is not the most swift and certain apps skate skate ... again ... and always skate to start while the appearance of certain interface elements on the screen is the opportunity to see beautiful saccades . And side games is not necessarily longer pink. Pinball FX train just sometimes viciously at the ball animations to render the game easily exploitable.

Delays beyond this are the many bugs that irritate random surface use. Thus this case where we tried several times to launch Internet Explorer on the desktop without success despite several clicks with the mouse on the screen or tapotis the browser does not just launched. This without displaying any error message or another. The same goes for the pause button on theDell Studio 1735keyboard Type Cover we pressed during playback of music and who has not had the desired effect despite several attempts. Another interesting bug: on our shelf and while we configured as French during installation, our country was set to UK in the Windows options. In fact the Windows Store posted prices in pound sterling. Everything is back to normal by selecting France as in the regional settings of Windows. Well, not really ... since the lock screen Modern UI continues to display the date in English "Friday 2 November" while writing this.

And what about an issue obviously ignored by Microsoft, that the timing of his pictures and his music? Surface is indeed delivered naked, without any cables or synchronization software. To you copy music, video, and more pictures via external storage media or a network drive on the shelf. Let us, however Microsoft the opportunity to broadcast their content through streaming or even from the Cloud for music. For some have a PCDell Latitude E4300on Windows 7 or Windows 8 and application Skydrive installed, you can view pictures and music to the distance from the tablet. The whole problem is of course that your PC must be on the road with a working Internet connection. For the Music app can increasingly enable synchronization with the cloud Xbox Music from the Settings icon and this time it is your list of music that is synchronized to the cloud with the legal provision proposed by Microsoft As part of its Xbox Music: here we find a kind of iTunes Match. Your music list has been synchronized with Microsoft servers and they allow you to listen to streaming wherever you are. Naturally, it will have the appropriate subscriptions, otherwise you will receive advertising.

We tested the HDMI output. It operates seamlessly except that it operates as a normal Windows PC. So in clone mode is the resolution of the tablet that is replicated with upscaling on the TV screen and it is frankly not nice to see ... Must switch the mode "second screen only" but in this case you lose the touch controls of the tablet which then manipulates the blind ...

Test start time gives an indication of the velocity of our shelves to be operational during a cold start. The results are expressed in seconds, the shorter bar represents the starting time of the fastest. Here, it takes 27 seconds to Surface RT to start with Windows while the iPad Mini is operational in 19 seconds as the third generation iPad (both iOS 6.01). However, it is better than 40 seconds of the Galaxy Tab 2 10.1 Samsung.

Surprise, the SunSpider test gives good performance for Internet Explorer (both desktop environment that Metro). Surface and Windows RT climbed into second place behind the iPhone 5, which is the fastest. This is definitely a step ahead of the iPad here are a little behind.

It should be noted that SunSpider is dependent on the browser and it is the only test reproducible performance that we can drive on surface, the usual tools like GeekBench or Linpack is not available on the Windows Store.

It ends with autonomy, with playing a video loop,inspiron e1505screen brightness set to 50%, as the volume, keeping Wi-Fi active. Living here is doing very well with a range from 11 ... provided that the iPhone 5 and therefore better than that observed with the 3rd generation iPad.


For a first tablet, Microsoft shows that the expertise of its hardware division in charge of the design of keyboards, mice and webcams for years is actually real. With his finish, the tablet has certainly not ashamed to face competition. The equipmentDELL Latitude E5410is at such a product and if we can regret the lack of HD screen, we retain the use of a quad-core processor Tegra 3 or the presence of two cameras without HD 720p forget the USB port and HDMI output (the latter requires optional cable). Better, Microsoft really innovates on the material system with integrated stand that allows worry-free and without lugging accessory put the tablet on his desk to the vertical at an angle it is true fixed. The unit is robust and inspires confidence. Microsoft has also a very good idea to propose a system keyboard surface. Two models, one touch, the other mechanical keys with two very different sensations and sometimes acclimation time as we have seen.

But behind these really good ideas hiding serious deficiencies. And finally the problem is not so much space hardware and software ...! RT Windows is very similar in status to an operating system in beta so bugs are numerous and glaring. And, after a few minutes of use. Not content to be buggy, slow Windows RT displays flagrant moment. Difficult here to say whether this is partly due todell xps m1210Chick 2GB of RAM tablet. Of course over time Microsoft will successfully return a set of problems. However, the manufacturer will not return to the storage capacity and the fact that our model 32GB, only 14 GB are actually available to the user (!).

To all this we must add a size issue: the software environment. RT while Windows is not compatible with Windows applications that have existed for decades, the only way to get apps is the Windows Store. A store today and provided little less since all RT for Windows applications developed for Modern UI and Windows 8 are not always compatible with Windows RT. So yes of course, Living with Windows RT unbeatable argument: Office Suite 2013 is supplied as standard (what does the European Commission and the DOJ?) And offers the same experience as on a PC and the same level of functionality and compatibility . Rest Outlook and Publisher are lost during porting. And if we may venture to comment controversy: whether to use RT Office must go through the office and have a keyboard or Touch Cover Type ... use as a traditional laptop, right?

Ultimately, despite a practically flawless execution on the material plane, and real innovations, RT Surface with Windows now seems not ready for the general public. The problems listed are too numerous and disadvantageous to Surface a tablet that can be highly recommended, not to mention the problem of complex software environment. In addition, thedell xps m1710 batteryprice seems a bit high, 489 euros the 32GB model without a keyboard, keyboard with 589 euros, it is certainly comparable to the price of a Pad Transformer Infinity ... But with only 14 GB usable in the end. Of course it will be interesting to see how Windows operates and RT if applications are emerging ... And if the system does not seem viable today, hopefully Surface opens the way to Windows tablets RT more convincing. Of course, we expect firm footing Intel variant surface to see how it is positioned.

Full Test Nokia Lumia 820

Lumia 820 takes place on the medium-high range - due to its sheet - and strengthens the family of smartphones Nokia to Lumia 920 Lumia. Sold for 470 euros off grant, is a little less expensive than its elder, it is powered by the Windows Phone 8 system with a 4.3-inch (800 x 480 pixels) AMOLED screen, a Snapdragon S4 processor dual-core clocked at 1.5 GHz, 8 GB internal memory (over 7 GB available on SkyDrive) expandable via a microSDHC card, and a 8 megapixel sensor. Is Lumia 820 a good smartphone? The HTC 8 X which it faces a competition? Response in this testbed...

Lumia 820 displays a design of a clean, appealing to the eye but not frankly innovative genre - except perhaps the wide choice of colours.

Unlike the 920 Lumia, unibody, Lumia 820 has a modular shell (accessible battery, therefore, but SIM cards and memory pinned under the battery). what change the color of hull to the envi.

Is however preferred to touch gum, less rolling coatings.

Side stencil, the phone is not in the ultra-finesse or the lightness (160 grams anyway), but it fits in the Palm of your hand. Compared to the 920 Lumia, largest (4.5-inch screen) and heavier, it is obviously much easier to use regularly in one hand the 820. An important point for many users who do not wish to upgrade to a smartphone too big.

The 4.3-inch screen is equipped with a limited definition of... 800 x 480 pixels. At the present time, competitive, the density of pixels displayed here is clearly indented. A surprising choice on the part of Nokia. It is indeed not an entry-level smartphone... In front, its direct competitor the 8 X is equipped with a 4.3-inch screen also but with any other definition of 1280 x 720 pixel - identical to that of the 920 Lumia.

If the contrast ratio is very good, the maximum brightness is indented, with only 284 cd/m², against 410 cd/m² for the 920 Lumia, 374 cd/m² for the HTC 8 X and 500 cd/m2 for the iPhone 5. In terms of Colorimetry, the 820 is less faithful than his groin with a Delta E 7.4. A large majority of recent smartphones displays one of below 4. As a reminder, most the of of a screen approaches 0 and more true-to-life colors it displays.

The screen shows reagent and perfectly obeys the solicitations.

It should finally be noted the excellent initiative on the part of Nokia: allow owners of this phone (and Lumia 920) for use with gloves, with accuracy always last. A real plus for winter days! Would say, competitors, if you could provide the same treatment to all smartphones and tablets in the future, users in know you strong gre.

Interface and navigation

Windows Phone 8 is not a clean break compared to the 7.5 version. So far, the OS is evolving and offers now a few new features common to all terminals launched under this very nice system to use. We have compiled and detailed each of them (SkyDrive to share the calendar, notes, photos with different groups of contacts, the world of children, etc.) on this special page Windows Phone 8. Remember WP8 takes over the forces of WP7: integration of a suite agency link with an own account with 7 GB of free online storage on Skydrive notes to unify notes taken on the fly.

The range Nokia Lumia has many exclusive applications such as Nokia Transport, Drive Nokia, Nokia Music, or even Nokia Explore. All of these services offered free of charge are particularly significant, because effective and thoughtful like Nokia maps mapping system - common, itself, to all Windows Phone.

If Windows Store is not yet as well-stocked as iOS, in terms of games in particular, we appreciate to all test them, even those who are to be paid. SmartGlass app allows to enhance the experience on the side of video games to control an Xbox 360 (also available on Android and iOS app).

A few stars applications are still not on the shelves of the Store Windows. It notes, for example, the absence of Instagram and DropBox (but does have SkyDrive, share its data in the cloud).

Lumia 820 displays a beautiful reactivity and a nice fluidity in all circumstances (download apps, surf on the Internet... video playback), even when multiple applications run in the background. The integration of a stable system to a solid and well optimized technical configuration delivers good results and good behavior of the terminal on a daily basis.


Awaited for its qualities as excellent stamped photos by Nokia, Lumia 920 we had disappointed, with a non-homogeneous rendering and the marketed these last six months high-end smartphones below clearly. Lumia 820, also equipped with a sensor of 8 megapixel is doing better? Well frankly step. There again, it's disappointing. It is certainly a hair better than older, somewhat less blurring and therefore more details posted on the edges of the shadow, but overall, it remains unsatisfied. The picture function will clearly not be the decisive factor that we would opt for this smartphone.

Windows Phone HTC 8 X, despite increased a bit exaggerated contours, is doing better and displays including more details on the whole image.

Finally, while Lumia 920 was doing very well in low light, 820 does it less well, but with a little light and without flash, it can get out of the correct images due to light conditions.

Lumia 820 takes advantage of some applications such as photo welcome such as Panorama and PhotoIntelligente, to create a picture "that's Alright" from captured shots.

The quality of the video catches (so far in 1080p) is quite correct for a smartphone with a significant sound rendering.

The headphone output provides a high-performance sound reproduction without any distortion of the sound, all with good dynamics and a fairly correct maximum power. The external speaker is struggling to escape, with a notable saturation at high volume.

Equipped with a battery of 1650 mAh, Lumia 820 held fast the day with enough sustained use (SMS, Web, social networking, music, picture). Games and video, particularly intensive in energy resources, are more quickly lowering the autonomy of the device.

Galaxy S III: the new smartphone reference?

Spearhead Samsung Galaxy S III is simply the most anticipated Android smartphone of the year. The wait is over: here in our hands. Is it a worthy successor to the Galaxy S II?

In 2 years, Samsung has upset the landscape of Android smartphones. Party after HTC or Motorola, the Korean manufacturer has unsheathed a 2009 Galaxy S which has found a winning formula: design from all but the top components, a screen large enough and flashy to high printing, and it must be confessed, a certain resemblance with the iPhone in both lines in thedell Studio XPS 1647 batteryuser interface.

Upon its release, the Galaxy S was nevertheless opposed to sharp competition: HTC was including in front of smartphone performance, but also better finished, as the Desire HD. However, Samsung has widen its lead with the Galaxy S II, a successor signing ultrathin, lightweight, and benefiting from a dual processor heart. Become a reference in its domain, the Galaxy S II has naturally created a strong expectation of his successor. The latter was also awaited for ... By Apple, which has meanwhile released its legal arsenal to defend its patents and design.

However, Samsung has taken its time to unveil the Galaxy S III, leaving especially enjoy HTC's Mobile World Congress to get its new line One: no need to rush, since Samsung can now impose its own agenda. After mounting the buzz, the manufacturer can finally unveil its new baby!

Therefore more hype, but a true smartphone that will have to face competition. On paper, you could be disappointed by some technical and aesthetic choices of the Galaxy S III. However, upon closer look, the new Galaxy S may well impose natural successor to the GS II on the throne of best current smartphone.

Equipped with a quad processor heart home, Exynos 4412 Quad, a Super AMOLED screen with a resolution of 1280x720 pixels and a photo / video sensor 8 MP/1080p the Galaxy S III runs Android Ice Cream Sandwich . As usual, off Nexus S and Galaxy Nexus, Samsung has "customized" using its interface Touchwiz overlay, modified for the occasion. It's not just because the smartphone embeds some additional keys, including S-Voice, a voice assistant that is reminiscent of some memories ...

Design and ergonomics

Samsung was expected to turn on the design of the Galaxy S III. IPhone 4 to the latest HTC smartphones through the N9/Lumia Nokia 800, we have witnessed in recent years a move towards more materials and design quality "unibody" focusing on the fineness and uniformity ... to the detriment of caches and removable covers. We therefore asked whether Samsung would not take and break theDell Latitude E5400 Batteryplastic design of the Galaxy S II battery cover and rather ... low end. And the answer is negative: Samsung continues its momentum and renewed with the S III his own style. The hull of the smartphone is fully plastic cover keeping it thin, flexible plastic that can scare the first time you retire, but remains firmly in place, without play or cracking.

A short tour of the phone reveals the most classic choice: there is a 3.5 mm jack on the top, a micro USB port at the bottom of the hull, the volume buttons on the left and the lock button on the right. On the back, the camera / video is elevated relative to the rest of the hull, and indeed quite exposed to scratches. It is surrounded by a LED flash and a speaker. An objective video is on the front, with two sensors on which we will have the opportunity to return. Invisible in normal operation, the LED through the hull to blink when charging and notifications.

Thisdell latitude e6400 batteryapproach may therefore seem conservative, but it has an advantage at a time when more and more manufacturers seal their shell, Samsung continues to opt for a removable battery. We still regret the rim plastic imitation brushed metal: a bit of metal on a real high-end smartphone was not too many. But Samsung is Samsung, and if the materials used are not the most luxurious, all is well finished and inspires confidence when assembled.

The balance is quite successful outside: therefore move the components that drive the Galaxy S III, because this is where Samsung traditionally shines. After the Tegra 3 HTC One X, Samsung followed suit with no quad-core version of its Exynos home: Exynos 4412 Quad. This SoC ARM v7 is composed of 4 core Cortex A9, clocked at 1.4 GHz. The chipset is engraved in 32 nm. Compared to HTC One X is a little better on paper: the hearts of Tegra 3 operate at 1.3 GHz when used together, and spend 1.4 GHz when only the heart is used. In contrast, no pseudo fifth heart for low energy consuming tasks little.

Dell Inspiron 1320GPU SoC is a Mali-400 MP4, responsible for leading a 4.8-inch Super AMOLED screen with a resolution of 1280x720 pixels and a resolution of approximately 306 dpi. Characteristics reminiscent obviously the Galaxy Nexus S III screen is slightly larger (4.8 against 4.65 inches) and pixel density a little lower, the Nexus amount up to 316 pixels.

As usual, critics criticize him its Super AMOLED oversaturated colors and features AMOLED display that reveals a small frame on the screen, still much less visible than on a Galaxy S II, Due to the resolution denser. However, the colorimetry of GS III is still more convincing than its predecessor, and the viewing angle is simply impeccable.

The camera offers some common characteristics for a high-end smartphone: sensor retro-exposed pictures of 8 MP, 1080p video, and features that seem to be common: f/2.6, focal length of 4mm maximum aperture of 2.76 mm. These are features quite satisfactory for a smartphone, and we'll see in practice that the photos and videos take all their promises, but one could imagine that Samsung is playing brinkmanship and pass the bar as 12 MP Sony Xperia S andDell Studio 1558 Battery.

In front, there is a goal generating video still shots of 1, 9 MP and 720p videos. Both sensors operate at 30 frames per second.

No change either on memory and storage. Regarding RAM, 1 GB is found, which is the maximum of the current smartphones. The phone is available in 16 and 32 GB and storage capacity can be expanded with a MicroSD slot that can add up to 64 GB! A good point, especially since HTC has removed the possibility of extension on its terminals One.

We arrive at wireless, and what more, if it is that Samsung has thought of everything? We pass on the 3G: HSDPA (21 Mbps) and HSUPA (5.76 Mbps) are supported. Ditto for the Wi-Fi compatible B, G and N. Bluetooth 4.0 is the game, and manages the GPS A-GPS. Classic, what ...

What is less, even if the Galaxy S III is not the first Android smartphone to integrate, it is the presence of an NFC chip: it is especially designed to work with two integrated applications: Android beam, which is part of Ice Cream Sandwich, and S-Beam, an application for transferring files from Samsung, not working for the trouble between two Galaxy S III. A quick glance at the sensors to finish: the phone has an accelerometer, gyroscope, proximity sensor, compass and ... barometer.

Galaxy S III runsInspiron 1464Android Ice Cream Sandwich, version 4.0.4 to be precise. Unsurprisingly, the manufacturer does not Android in its basic version, as on the Galaxy Nexus, but mostly with its TouchWiz overlay, or more precisely a variant exclusive to the Galaxy S III. If you have a Galaxy S II ICS in the past, you will have noticed that the differences between 2.3 and 4.0 are strongly erased.

The variant of the GS III named Touchwiz Nature, however, is more radical in its changes, and finally closer to the original spirit of Ice Cream Sandwich, as it was designed by Mattias Duarte, as imitation of iOS Touchwiz original. Should we see again a desire to avoid the wrath of Cupertino? Whatever the reason that prompted these changes, they are welcome, because the interface is both pleasant to use, while retaining the simplicity of the ICS "vanilla".

Before going into the details of the interface, however, a difference back to the fundamental shot between the original spirit of ICS and the Galaxy S III: the virtual keys are not integrated into the interface as the Galaxy Nexus or Android tablets. As was mentioned earlier, Samsung has chosen to renew its usual ergonomics: a central physical button and two touch keys. The center button serves several functions: a simple press returns to the home screen and long press opens the list of recent applications. The twoDell Vostro 1520softkeys are assigned to the parameter display, and back. ICS purists may prefer the Google approach, where we have a dedicated button to display the Application Manager, but can not find the time needed to hold down the center button too long. However, this change has a second consequence: the use of a smartphone button to display the options, while the practice advocated by ICS is more access to settings from the icon in the upper right of the interface.

Overall, the interface of the Galaxy S III is conspicuous by its simplicity. Samsung has sold a few effects such as scrolling carousel screens receptions reminiscent Sense, or manager of browser tabs Coverflow way, but in general, it is far from a Sense 4 which redraws all ICS sauce: Samsung, for example, kept the task manager minimalist and intuitive from the standard version of Android 4.0. In addition, we always appreciate the presence of shortcuts to disable the various circuits directly from the notifications panel.

Samsung additions occur especially in applications provided, as well as various small features added here and there, including using proximity sensors. All are not really necessary, and some even suffer a functioning quite random, but include particular Smart Stay, a feature that uses the front objective to detect your face, especially your eyes leave the screen on, or instead it off if you do not look. Other gestures are included rather original: Wear your phone to your ear after reading an SMS to call the recipient, place theVostro 1015screen side to disable ringtones ... Why not!


We will not stop raving about the telephony layer, but simply say that we did not notice any problem call quality is there, transmission and reception, and not worry proximity sensor that would cut a call inadvertently.


Key Samsung is also reflected in the media, and lose nothing of the main strengths of the Galaxy S II's video support seamless. The reader has a home provided DivX Certified, and therefore reads, without adding a third player, almost all videos that gave him: DivX, Xvid, MKV, H264 ... And what is more without re-encoding necessary.

We note in passing rather original functionality: the ability to display a video "picture in picture" over any application. It may seem a little gadget, just to show that the Exynos Quad was in the belly, but one can imagine cases where you want to keep an eye on a video while doing something else. However, the interface of a smartphone is not made for it, we never know where to place the window. It might be more interested on a shelf.

On theDell Inspiron 1521output video to the TV, the Galaxy S III provides an HDMI output via MHL protocol, but with one caveat: Micro USB connector with additional pin, it will be impossible, as we made the sad experience of use the adapter of the Galaxy S II. And in the absence of new adapter when our test, so we did not test this feature. In contrast, no problem regarding the DLNA, which works exactly as expected, and without a hitch.

The audio is a little less difference, even if Samsung provides a pleasant drive to use and feature rich enough: it manages profiles preset equalizer, but a real equalizer preset to suit his tastes. On this point, Samsung has not eroded the basic features of Ice Cream Sandwich as did HTC Sense on the 4. In addition to equalization, Samsung has also included some more or less useful effects: the spatial and improving clarity, so X-Fi, are quite effective, but adding reverb is superfluous. We regret, however, since the power of the processor allows clear lack of management fade or play "gapless". However, the alternative is no shortage of players on the Play Store for more picky. We note in passing that thexps m1530retains the FM tuner of its predecessor. It is always better than nothing.


We will not dwell on the Internet, because it is absolutely no surprise: there are Google applications (web browser, mail client Pop / Exchange / IMAP, Gmail ...), and not much more. The web browser has a few "customizations" made in Touchwiz: tabs, for example, displayed horizontally and in 3D, so HTC Sense. However, unlike Sense 4, Samsung has not cropped on the boundary already binding, 8 tabs. We may regret the absence, by default, support for Twitter and Facebook, not even through a widget: Google+ is logically put forward.

Obviously, the screen of thedell xps m1330is a treat for surfing and Ice Cream Sandwich forces, fluid scrolling and zooming is perfect. Despite the abandonment of Adobe Flash on mobile, you can always find a compatible version of ICS on Play Store, and again, videos and animations are no problem fluidity. It took until the monsters power as GS III to finally have a plug-in that delivers the performance expected of it!

Not much to complain about either side of the game: the higher resolution of the Galaxy S III is not flinching GPU Mali 400 MP4. The few games tested, including Riptide, Shadowgun and Dungeon Defenders are rotated perfectly fluid. In contrast, the presence of tactile buttons on the bottom of the unit increases the risk of accidental pressing holding the smartphone in landscape mode: we arrived to operate the Menu button during game in Riptide.

S-Voice: a clone of Siri without genius

The gossips say that they could not help it: the Galaxy S III incorporates its own alternative to Siri, the voice assistant in the iPhone 4S. The concept is the same, and application design is largely inspired from Apple: the bottom of the screen icon microphone can start a voice request. Once the above stated, it is sent to the server with a latency Samsung, and executed with a return speech.

S-Voice handles requests altogether classic call a contact, send an SMS, create a memo or event title play on the MP3 player, launch an application, search or learn about the weather.

In practice, we found imperfect speech recognition, especially for names. The application includes commands correctly but often tangled brush as soon as you place a contact, artist or song title in the equation. On this level, Siri seems more powerful, but still far from optimal though.

The problem ofDell Inspiron 1520S-Voice, it was his lack of personality. Already, nasal voice is quite unpleasant. But above all, Samsung has not been able to reproduce what is part of the effect of "wow" Siri: humor and feel that exudes intelligence, even if it is absolutely not. S-Voice knows he has to respond to requests, and answer "I do not understand" when he does not speak English with a French accent for no reason. Do not try to be funny, or ask questions in a roundabout way, you will hit a wall.

In short, if the original is already more or less a gadget in the current state of things, this pale copy unoriginal and not more effective, even somewhat less, is even more futile and does nothing. That is, just to say that Samsung has its own Siri, and that's all.

Galaxy S III is equipped with the latest in family Exynos. How is this processor quad heart "home" clocked at 1.4 GHz compete Qualcomm, NVIDIA and ST Ericsson? To find out, we conducted all our usual benchmarks. Start with the processor ...


Linpack is a benchmark that evaluates the power of the processor. The result is expressed in millions of floating point operations per second (MFLOPS). Compared to Benchmark Pi, the main advantage lies in the possibility to test multi threaded (multi-core processor so).

The single and multi threaded tests remain largely dominated by S. HTC One The dual-core SoC Snapdragon S4 Krait (1.5 GHz) Qualcomm does wonders managing to hold a candle to the quad-core Exynos 4412 (1.4 GHz, Galaxy S III) and Tegra 3 (1.5 GHz, HTC One X).

Multi threaded, the Galaxy S III ascended still the second step of the podium almost tied with the iPhone 4S (A5 SoC, double heart 800 MHz).


Web site with SunSpider, the authors of the benchmark JavaScript HTML rendering engine Webkit (Safari, Chrome ...). Galaxy S III lets talk powder by winning the high score ranking. Good results are confirmed by practice. Surfing is perfectly smooth in all circumstances.

GL Benchmark (Off Screen)

GL Benchmark evaluates the performance of the graphics terminal. Offscreen test is independent of the resolution. Here, the Galaxy S III again won the race, ahead clearly HTC One X and other iPhone 4S.


The Galaxy S III has a 2100 mAh battery, which is supposed to guarantee a good autonomy despite intensive components. And it is true in practice: on our test autonomy in use, it ranks third position behind the Huawei Honor and the Motorola Motoluxe, two smartphones much more modest. It is also better than its closest competitor, the HTC One X, which is still much better than leaving the road.

Photo / Video: the software part

Before detailing the performance of the Galaxy S III pictures and videos, make a turn on the software, which is always full. Among the many options available, it will benefit from a timer, some scenes (sunset, sport, indoor, fireworks ...), a burst mode, an HDR mode, the settings of parameters such that the exposure or sensitivity, scenes, macro mode, and some gadgets like smile detection.

Performance picture

No 12 MP for Galaxy S III, then, but that does not mean, however, that the photo and video sensor is recessed. Let us recall briefly the characteristics of the sensor back that we used in our tests: it is rétroexposé, which provides better sensitivity even in difficult lighting condtions, and goes up to 8MP photo.

Speak now practice. Very simply, the Galaxy S III displays excellent image quality, among the best we have ever seen on a smartphone.

It begins with our test scene, which allows us to immediately note two characteristics of the lens. Firstly, the very high accuracy of the images produced: one can quibble around the edges a little less well defined, but it is the case of all sensors of smartphones, and the gap is far be obvious. We also note the side very flattering colors and contrasts: it is certainly a little less saturated than it looks on the Super AMOLED screen of the mobile, but the images are a bit more "flashy" than in the real life.

The exterior is also an opportunity to test the rendering device in HDR mode, and again, we are amazed: the responsiveness of the device, apparently supported by the processor quad-heart is so remarkable that it took several shots to inspect realize he took out two different views.


A year after the release of theInspiron 1720 Battery, which probably remained, until very recently, the best Android Smartphone available, his successor he managed the handover? Certainly, yes! The qualities of the Galaxy S III are numerous, and so we will start with what leaves us cold, namely the design and finish. Of course, once in hand, the Galaxy S III is much less "cheap" it looks on paper. The design is not the most original, even if you feel that Samsung has at least made an effort to move away from the lines of its predecessor, but on a smartphone sold over 600 euros, we still expected a little more luxurious than glossy plastic shell with a metal rim in imitation.

Fortunately, Samsung catches up with a few surprises of his choice: the phone is almost as light and thin as the Galaxy S II, while a portion of smartphone users will appreciate the presence necessarily a removable battery and a Micro SD slot. In addition, if your back is weak, the facade Gorilla Glass 2 is excellent. However, it really reached the limits of use in terms of size: despite the undeniable comfort of the 4.8-inch screen, we meet as the Galaxy Nexus or HTC One X situations or use a hand is uncomfortable, especially forDell XPS M2010users with smaller hands.

One could also criticize some software additions that do nothing, as S-Voice, a botched clone of Siri that is not better than his model, though not very brilliant, and that is even worse. In the end, the functionality will only give grist to critics that Samsung will surely ironic about the plagiarism.

So what we have to blame the new flagship of Samsung. Else is simply the best of what we can expect from a smartphone in 2012. The processor quad-heart Exynos 4412 Quad explodes almost all its competitors, with the exception of S HTC One on some tests. The graphical part is not left: Mali 400 MP4 obtains excellent results. Regarding performance photo and video, the Galaxy S III is faultless: the images produced are accurate, the camera is a perfect response, especially with regard to gusts and HDR videos are fluid, responsive development ... We look good, there is nothing to complain aboutDell Inspiron 1721 Battery!

With a 4.8-inch screen (1280x720 pixels) and a quad-heart, one might have feared for the autonomy of the smartphone, but again Samsung ensures: 2100 mAh battery there is probably not unrelated.

Finally, the software has not been neglected: the photosensitive layer is rich in features, video player, DivX Certified, swallows all videos that he has provided, regardless of the format and definition, and audio player provides the essential (equalizer, enhancing effects and spatial ...). The overlay software is in sobriety: Samsung has adapted its Touchwiz interface conventions of Ice Cream Sandwich, with which he nevertheless takes large liberties, and provides an interface that is both simple and enjoyable, even if purists regret the disappearance part of "true" ICS.

In the end, theStudio 1535 Batteryappears in fact in line with expectations, but certainly below fantasies that buzz before its launch had been generated. It is, finally, a product Samsung's invoice is classic, but its performance is impeccable, and its full functionality. Its size XXL will not suit everyone, but the smartphone will satisfy those for whom it is not fatal.

Review - II Galaxy Note

There is this one year, the Galaxy Note has emerged on the market and Samsung has sold more than 10 million copies. But a year in the world of mobile phones is a Samsung Eternity and is launching a new version of its Galaxy Note. Say hello to the Galaxy Note II.

At first glance and when you hold it in your hands, you can see that the Galaxy Note II resembles the popular Galaxy SIII. And yes, even his side plastic, which gives it a look of poor quality phone was replicated here. By cons, it does not mean that the phone is not solid or of poor quality. But this is definitely not a Lumia 920 or iPhone. This aspect does not discourage you, after all, more than 20 million people have procured the Galaxy SIII.

The interior of the apparatus, for its part, is solid. With its 1.6GHz processor quad-core, 2 GB RAM, internal storage capacity of 64GB and a possibility to increase this capacity up to 64 GB with SD card access, NFC and wireless access dual band WiFi 802.11n, Note II definitely has what it takes to appeal to people who want a powerful smartphone. The AMOLED screen of the Note II has a size of 1280 X 800 and offers a resolution of 1280 X 720. With all these specifications, it is normal that the Note II has a battery up to its specifications. The 3100 mAh battery offers a lifetime impressive. After using the GPS function for 45 minutes, making phone calls, surfed the web and took some photos that I shared on social media, I still had 69% battery on the Note II. Awesome! The camera, cons, good, but nothing more. You have a rear camera of 8 mega pixels that offers video in full HD 1080p.

The S Pen on his side was definitely improved, beginning with a notice that tells you that you have removed the S Pen from its base. The phone enters S Pen mode with a different interface, ready drawings or other commands pencil intelligent. Write with the S Pen is really nice. You feel like writing on paper so that the accuracy is there. The feature I love the pencil Air View that lets you navigate menus without activating, via your pencil on top of an icon, for example. A small dot appears on the screen and you will not only be more accurate but also view tabs (by making them move) without activating them.

The operating system available on the Galaxy Note II Android 4.1. So the Note II is one of the first phones with the operating system and Jelly Bean animations are definitely more fluid this time. Thank you, Project Butter ...

In the end, if you do not like the large size of the first Galaxy Note, you will surely not like the 5.5 inch Note II. I must admit that this is a little weird talking on the phone with this unit, but if you want a device with a large screen, you'll be happy. Otherwise, the S Pen offers very good performance and handy features. In addition to being a very powerful device, the Galaxy Note battery delivers exceptional performance for a smart phone.

Asus X53SC

As the Packard Bell TS11 tested recently, theVGP-BPS13/Suses a Core i3-2310M two.10 gigacycle per second and with GeForce GT 520. It embeds 4GB of memory as its challenger and offers an equivalent property. Asus X53SC however differed by many blessings as a tough disk of 640 GB rather than five hundred GB video memory double as giant, a a lot of powerful battery associate degreed an aluminium palmrest. The presence of associate degree aluminium giant on a portable computer to € 499 is sufficiently rare to be mentioned. Asus puts conjointly obvious with a technology known as \"IceCool\" that keeps this space still contemporary for max writing comfort. The X53SC is it the case should this season?

A history of K and X ...

Asus is absolutely not clear in its vary unless maybe be a part of fans of the complete WHO have down all references ... Thus, we have a tendency to check the X53SC is additionally listed underneath the reference K53SC. Besides, if you wish the X53SC on Asus web site, you\'ll not notice it! however you\'ll notice an equivalent K53SC and its specifications, drivers, application updates, new BIOS, etc.. tough to grasp what extremely makes the distinction between a X53SC and K53SC ... Warranty? Sales channel? Some sites advertise a guarantee of 1 year and 2 years for others an equivalent reference ... In observe, the X models square measure secured for one year whereas the K versions have coverage for two years. {we can|we will|we square measure able to} deduce that some records are incorrect or product that more defines the reference range secured, that more complicate things ... Besides the name X or K 53SC, models square measure outlined by a sequence of letters and numbers: SX104V within the case of our model. ThereSony VGP-BPS13A/Q Batterysquare measure varied references moult sometimes within the disc. 2 colours square measure within the catalog: black and silver (like ours).

Asus X53SC

Livery with grey and silver (aluminum part), the X53SC is somewhat classic. The shiny plastic cowl has patterns however as for the Packard Bell TS11, they\'re bleached and therefore the end is sleek. Examining the X53SC, we have a tendency to discover a style kind of like TS11. The disc takes up the correct facet in each machines and there\'s an equivalent boss within the giant hatch that covers the complete bottom front of the machine. The hinges are similar and equally effective. Overall, theDell Vostro 1015 Batterylayout of the ports is comparable between the 2 machines with a standard defect: terribly weak spacing which frequently prevents use of neighboring ports. the correct facet homes the X53SC Kensington slot, DVD burner, two USB 2.0 ports additionally as audio inputs and outputs. At left is that the giant grid of hot air outlet within the middle of the flank, the facility connective (but fortuitously the large catch is bent), the Gigabit local area network port, a VGA output, HDMI and USB three.0 port. The Mount Rushmore State card reader is on that at the front.

TheDell Inspiron 1520 Batteryencompasses a capability of fifty six,160 mWh capability is eighteen beyond that of Packard Bell TS11 (47,520 mWh). as a result of the elements square measure similar, autonomy ought to get pleasure from a directly proportional gain. Another pleasant surprise: Asus has equipped the X53SC one module of four GB of DDR3 1333 Hynix, that helps increase memory and avoid ending up with one or 2 bar (s) 2GB gratuitous case the upgrade. facet burner, there\'s a Matshita DVD-RAM 8x double layer universal UJ8B0 quite common. In terms of storage, this X53SC is provided with a Hitachi 5K750 640 GB Despite glorious transfer rate, the disc leaves no lasting impression as a result of they\'re aloof from reflective printing slowly than the prodigal arduous in actual use.

The power jack is angular imposing misplaced.

Incidentally, thisDell Vostro1088Batterycomes untufted. we have a tendency to don\'t even notice or maybe little optical mouse that came with several models. It ought to conjointly produce the Recovery videodisk (5 in total), associate degree operation that require one hour forty minutes ... facet packaging, Asus uses principally cardboard and plastic lowest (only many protecting films).

Making contact ...

With 2670 grams,Dell Inspiron 1720 Batteryis slightly heavier than average (usually but 2600 grams). There should conjointly add 466 grams of the large AC adapter that giant catches don\'t facilitate ... while not getting to refer little, this Asus is one amongst the \"smaller\" fifteen.6-inch with 378 x 253 x thirty three one to thirty four.9 mm. The grip is sweet particularly once the portable computer isn\'t connected to mains. Otherwise, the facility offer housed within the left facet is annoying particularly initially. With slightly observe, simply take the portable computer over to the front (or back). Anyway, this can be still questionable because the size of the outlet ...

The wrist joint and every one round the keyboard (the \"top box\") is aluminium. conjointly a pleasant bit, it offers a really sensible rigidity X53SC as well as higher than videodisk (weak purpose on several machines). The aluminium itself contributes to the impression of coolness to the bit however it\'s not the sole one. Indeed, vents placed within the front, just under the aluminium square measure transportation contemporary air and facilitate keep the palm rest cool even higher than the disk. IceCool technology isn\'t a pure invention promoting ...Dell Vostro 1510 Batteryin truth purposeful. The keyboard is supported by a Synaptics touchpad that supports up to a few fingers, a bit like the Packard Bell TS11. The bit space measures eighty five x fifty millimetre and every occupy separate buttons forty one x fourteen millimetre. If there\'s nothing wrong with the touchpad itself, the buttons may be terribly yelling with a \"clack\" unpleasant pressing their central half. By clicking on the ends, they\'re rather more discreet ...

The keyboard \"Chiclets\" is kind of nice with a decent resistance of the keys though it lacks overall rigidity. Asus has narrowed the numeric computer keyboard to keep up optimum layout of the alphanumerical half. within the aftermath, the touchpad (always aligned with the house key) is nearest to the middle of the machine. additionally to the multimedia system keys and management (sound and light) classics accessible via Fn,dell xps m1530 batteryhas placed some handy shortcuts like Fn + Enter to begin the calculator, Fn + house to change power modes, Fn + V to activate the webam software package or Fn + F9 to disable the touchpad.

The gills square measure coming into air at the front underneath the palm rest: IceCool result.

Thedell xps m1710 batteryshiny could be a AU Optronics B156XW02 V6 fifteen.6-inch HD (1366x76 . It may be summarized in one word: banal. Like all crystal rectifier Volunteer State panels, black is just too bright (close to one cd / m²) and therefore the most brightness of white is on the order of 210 cd / m², a distinction of roughly two hundred to one. the colour rendition is pretty tight overall and extremely uniform backlight. Incidentally, this can be precisely the same panel because the Packard Bell TS11 ...

If the Altec Lansing speakers signed square measure neither higher nor worse than the typical, 0.3 Mpixel digital camera X53SC of a calamity! Saw the image pixelated and extremely sensitive to the slightest amendment of sunshine, it\'s just about unusable. we have a tendency to had seldom seen as dangerous ... Thedell xps m1330 batteryrelated to software package isn\'t ready to even part correct shooting.


In performance of the processor, there\'s not rather more to mention in respect to the check of Packard Bell. The Core i3-2310 two.1 gigacycle per second offers little in nearly an equivalent edges as within the TS11 X53SC. Asus shows but no scores continually best however the gap remains the domain of negligible.

MacBook professional two011: Core i7-2720QM 2.2GHz | Radeon HD 6750 one GB | four GB

MacBook professional two010: Core i5-540M 2.53 gigacycle per second | GeForce GT 330m 256MB | 4GB

In 3D against the GeForce GT 520MX 1GB is a lot of safe than the GeForce GT 520M 512 MB although in each cases it\'s a DDR3 memory bus solely sixty four bits, the GeForce GT 520MX the Asus is related to the memory at 900 Mc, whereas that of Packard Bell is barely 800 Mc. additionally, the GPU frequency is completely different. GeForce GT 520MX the is clocked at 900MHz for the core and 1800 Mc for the shaders and 740 Mc severally against 1480 Mc for the GeForce 520M. With twenty first a lot of raw power and twelve.5% ​​more information measure, the GeForce GT 520 magnetic flux unit takes advantage of seven to sixty seven tough to clarify except by the extra memory though it\'s in theory not even necessary in 1366x768 with AA and AF ... The 1024 MB of memory could facilitate to avoid multiple \"swaps\" through the slim 64-bit bus and DDR3 that limit the transfer rate to fourteen Gb / s.

Autonomy and nuisances

Level of autonomy, thedell inspiron 6400 batterywill average slightly higher than the Packard Bell TS11: four h four h forty four against twenty two. Curiously, whereas they need similar instrumentation, Asus consumes ten Watts idle (we ne\'er saw less) whereas the Packard Bell all the way down to ~ seven watts. By cons, in standard usage, it usually oscillates between ten and fifteen watts in one case as within the different. Reading Flash 1080p X53SC consumption is fifteen watts as TS11. The fan runs endlessly X53SC at 2000 revolutions per minute however at this speed, low amplitude is roofed by the disc. within the workplace, it goes just about ne\'er steady. At some benches processor, its speed of rotation is high at 3800 revolutions per minute. It becomes sounding from 2600 revolutions per minute. additionally, every level of two hundred revolutions per minute produces a visible increase in noise.

Prime95, total consumption is thirty four Watts (like the TS11) however approach by combining seventy watts Prime95 and FurMark. underneath these extreme conditions, the mainframe and GPU square measure around seventy five ° C. Before reaching eighty ° C, the processor \"throttle\" and therefore the fan speed from 3900 revolutions per minute all the way down to 3000 ~ 3200 revolutions per minute. If the load continues, theDell Inspiron 1420 Batterysystem oscillates between phases of full power and idle.

In terms of sound, the X53SC emits ~ thirty three dBA at rest (measured at the amount of the top of a user to the machine on a desk). once the fan exceeds 2400 revolutions per minute, the noise becomes a lot of sounding than the disc. The amplitude may be up to $ thirty eight.5 dBA with the fan at 3900 revolutions per minute. In 3D, the X53SC isn't louder than the TS11 with thirty four to thirty six dBA varies games ... Finally,dell latitude d630 batteryas within the case of Packard Bell TS11, the fan noise isn't in the slightest degree sharp, could be a blast. there's no mention within the pitching noise\" or variations and frequent sounding fan speed for an equivalent purpose.

Windows seven sauce manufacturer ...

Dell Studio 14z BatteryLike any self-respectful portable computer, the Asus comes with a Windows seven 64-bit Edition and a decent layer of bloatwares. From a manufacturer like Asus tends to spotlight the performance, it\'s ironic ... If Power4Gear is sweet and convenient, merely make a choice from four modes saving terribly easy to enforced directly via the choices of Windows seven. LifeFrame3 is \"essential\" to the extent it\'s necessary to get pleasure from the terribly poor digital camera. Live Update two simplifies updates drivers whereas Winflash is important to update the BIOS. once five videodisk restoration inscribed AI Recovery is not any longer helpful. the remainder of the program is useless, or a minimum of not much: Asus Color sweetening, ASUS quick Boot, ASUS Fancy begin, ASUS sensible Logon ASUS Virtual Camera, ASUS Wireless Console three, ASUS figure, eManual, eDriver, Google package & Toolbar workplace 2010 Starter, Power2Go v6, Trend small atomic number 22 Trial, Windows live4 package & Toolbar and nicety PDF. once could be a portable computer while not bloatware?


Testing a second transportable least € 499 confirms what we have a tendency to had already ascertained with the Packard Bell TS11. Thesedell inspiron 9400 batterymachines with a Core i3 2310 and GeForce GT 520M (X) provides performance so much superior to this desires of the workplace, will play in friendly conditions and supply sensible battery life (than the primary Centrino laptop). The presence of the Optimus technology conjointly makes it potential to reconcile autonomy and performance utterly. additionally, the cooling system designed for a mainframe and an obsessive GPU permits for quiet machines once the mainframe is employed with its IGP ... within the case of the X53SC we have a tendency to enjoyed the \"top box\" aluminium, excellent chassis rigidity and ensuing \"effect IceCool\" the palmrest. the massive multitouch touchpad is additionally terribly nice however the buttons square measure yelling. though it lacks rigidity, the keyboard provides excellent feeling through the touch keys. the additional power provided by the 3D GeForce GT 520MX 1GB is a lot of compared to the Packard Bell TS11 and therefore the presence of one strip of four GB is additionally a plus. is way less appreciates against the position of the facility connective, the fat intake elbow and imposing adapter with grounding. The Centrino N a hundred wireless card is additionally quite dissatisfactory at transfer rates. Anyway, the X53SC could be a sensible decide because the TS11, every with its perks and flaws. Given the costs, it\'s not cheated!

Dell Vostro 3350

Dell Vostro 3350 sign, an ultra-portable, originally designed for business, but who can claim to meet nomads in search of a 13.3-inch rugged and powerful.

The Vostro 3350, also known as V3350, presents an elegant way. In the grip, you do not notice any problem finishing, if it is a cover which shows a little soft with the feeling of robustness that emerges from the rest.

The hp pavilion dv6keyboard is chiclet keys made. They are well proportioned and well placed, providing a flexible and instinctive strike which minimizes failures and makes use pleasant.

The multi-touch touchpad also won favor with our correct size as much as glide nice and accurate. To avoid spoiling anything, the buttons are well established and do not give the impression of softness that sometimes found on other models.

Webcam (720p) capture movement so a little fuzzy. For the rest, it works wonders. It offers a good level of detail in the dark without burning white. The colors are well rendered. In short, it is an excellent model.

Despite the 13.3-inch size, the connection is complete. On the left are two USB 3.0 ports, and a DVD burner drive. On the right place the HDMI and VGA outputs, a USB 2.0/eSATA combo port, and microphone and headphone jacks. The SD card reader is placed before the power plug and on the back.

The ventilation system V3350 is quite effective. Even full stress components, the machine does not exceed 40 ° C. We appreciate unless he evacuates the hot air on the side and the rear. This may make unpleasant use when placed on the lap, or when using a mouse plugged into USB. Evacuation between the screen and the frame would have prevented this from happening. Side noise, background sound will be necessary to forget the V3350. In a quiet, the fan can be heard in any system activity.

With the 484170-001Core i5-2410M, current use is fluid (office, internet browsing, ...), but it also allows to perform image editing, encoding HD video or any other activity that requires heavy calculations in a reasonable time.

Video playback in high definition (HD 1080p Blu-Ray equivalent) passes smoothly on this computer. We recommend to use this for video playback capabilities of the integrated graphics (Intel HD 3000). This hardware support to decode Full HD 1080p videos without taking the processor is then free for other tasks.

Starting the Windows 7 Professional 64 bit integrated takes 42 seconds. It then takes between 10 and 20 seconds for the launch of various software and connecting to a wireless network complete extinction takes less than 10 seconds.

The graphics chipset capabilities are weak. Inefficient in 3D, it can still run recent games like Starcraft 2 or Call of Duty Modern Warfare 2 with graphic details to a minimum, not a fan's dream game, except maybe those who practice retro-gaming or just 2D.

Audio: mandatory helmet!

But what is going through your head when Dell engineers have developed this computer? Inputs / outputs are among the best encountered lately. Crosstalk and dynamics approaching 90 dB. The output is quite good for a small laptop. Everything was perfect until ...

It ... realizes that the speaker - there is only one! - No use at all. At maximum volume, the sound is so low that it would be almost engulfed by the fan noise. Suffice to say that any keystroke prevents understanding. The helmet is mandatory for a chat.

With its 8-cell battery, theToshiba PA3817U-1BRS is offering a range of 5:20 (Wi-Fi off, headphones plugged in and brightness at 100 cd / m²), an excellent score. If its weight does not exceed 2kg - it weighs 2.1 Kg - it could be a good companion for travel. There, in a backpack or a bag, it is felt after less than an hour ride. Another black spot, the battery protrudes from the chassis, which can interfere with insertion into a cover like "second skin". By opting for the 4-cell battery, you gain weight and space, but we will sacrifice half of its autonomy.

The slab is V3350 mate. Outside, the sun does not create too much glare. A good place for him.

Its 13.3-inch diagonal displays a definition of 1366 x 768 dots. The characters are easily readable.

The technology used is TN, with a persistence time equivalent to 5 ms models. As a result, viewing angles up and down are short and sufficient reactivity for office use and for movies.

However colorimetry poor. The colors are false, with a difference (DeltaE) of 13.6 and a strong colorimetric shift towards blues. Contrast is also bad - as with most laptops of the moment - with a rate of 155:1. We measured a black level of 1.31 cd / m², a white 202 cd / m².

If our color profile, available on Digital Focus is always there to correct those ugly colors, it can do nothing for contrast.

Dell Studio XPS 1647

eserved for the wealthy few years ago, buying a laptop to replace and / or supplement the desktop is an option that should be considered now. In fact the price of concentrates technology has greatly decreased due to lower prices of LCD panels.

Of course, the main interest of a laptopDell Studio XPS 1647is its very small footprint compared to a typical desktop computer. However, this space is expensive especially due to the miniaturization of components, but offers certain advantages related to mobility. With their multimedia options (17-inch screens, powerful graphics cards and other DVD players / recorders integrated ...), the least we can say is that the latest models of laptops have almost nothing to envy the great. To go directly to the buying guide laptopsDell Studio XPS 16and our selection of templates, click here.

The negatives of the largest laptop compared to desktop computers are:

The price is still higher by about 20 to 30% performance comparable (very approximate figure only serves to give an idea).

Lower performance, especially at the 3D (for games) and the limited speed of hard drives in the 2 "5 inches (often 5400rpm).

Scalability: we can not change that very few components on a laptop to share the memory and the hard disk is more generally quite expensive. Graphics cards are mostly soldered on the motherboard which prevents any upgrade.

Now that your choice is made, you have decided to purchase a laptop computer, you just have to choose. But not easy to navigate in this jungle where prices range from 250 € to 3000 €! The purpose of this guide is to help you choose theDell Studio XPS 13 Batterythat best fits your needs and your budget. Firstly some important points to consider:

1.1 The choice of the diagonal of the screen (transportable laptop or ultra-portable?)

It is necessary to determine whether you need a laptop, a portable PC (also called desktop replacement) or on the contrary ultra-portable PC see a netbook. These terms are used to define the four major categories of laptops that are currently in stores:

The transportable, as their name suggests,Dell Studio 1555 Batteryare a heavy weight (over 3 kg) and generally have little autonomy (about 2 hours in office use). This is especially models with 17-inch screens (see 18 or 20 inches), the difference in terms of weight and size with a 15-inch standard is far from being negligible (to take the train all days for example). Can be considered as models with 17-inch screens have a range of about 10% lower compared to a 15-inch model perfectly identical: indeed, the larger theDell Latitude E6400screen, the more energy it requires to operate.

Instead laptops are lighter and quieter and consume less energy (battery about 3-4h in office in accordance with the associated battery). Daily use of the device is the parameter which determines the choice of one or another of these categories. For travel very frequently, choosing a notebook lighter ofDell Vostro 1015and autonomous bring some comfort to the user. For everyday use at home with some travel from time to time, a transportable enough and provides comfort by its larger screen.

The ultra-portableDell XPS M1530: can be classified in this category are models that have a very small footprint and low weight (less than 2 kg). These machines are generally pretty quiet and autonomy is high, at least 4 hours in office. But the ultra-portables have the defects of their qualities: they are less powerful (debatable depending on model and size), theirDell Studio 1537screens are smaller (under 13.3 inches, the screen becomes quite uncomfortable to work long periods) and mostly they are expensive. Miniaturization and low sales volumes still make buying a luxurious ultra-portable even if the trend is a significant drop in prices in this segment. There are now powerful models (cpu and graphics card swift) andDell XPS M2010equipped with 13.3-inch screens that have almost nothing to envy their big brother 15 inches for the players, by cons it will cost at least 800 euros .

Netbooks:Asus EEE PC 701launched by the end of 2007, these small machines ultra lightweight (less than 1 kg) currently face a great success. Their performances are modest (entry-level processor, hard drives limited ...) but sufficient light for office and surfing for very competitive prices, from only 200 euros. These small laptops are often used for many users, see 2nd 3rd computer booster for heavy mobile. Since 2011, netbooks are very strong competition from tablets and smartphones, more and more efficient.

02.01 Graphics Cards:

Component to look closely at when buying a laptop is the graphics card. TheDell Latitude E5500graphics card is, unlike the desktop, almost always soldered to the motherboard (for reasons of space), it better not be wrong! For non-players, the choice has little importance, performance in 2D (desktop, DVD playback, surfing ...) will be roughly equivalent regardless of the graphics card. The integrated graphics solutions are well suited for cheap and consume less energy.

For those who want to play with laptopDell Precision M6400, this component is essential. There are still some interesting solutions include the current GT 540M, GT 630M, GTX 560M Nvidia are an excellent choice for gamers in the mid-range (models sold from 600 euros up to 1500 models with GTX 560M) and equivalent in AMD Radeon 6850M and 6870M's. Underperforming cards like the Radeon 6650M will be struggling in recent games but represent a more efficient solution that integrated chipsets for small budgets. For best performance, we must aimDell Studio 17Nvidia GTX 570M is very powerful, it is currently by far the best choice to play on models of laptops around 1500 euros.

For those seeking high performance, the ultimate solution is theDell XPS M1330GeForce GTX 580M and the AMD Radeon 6990 mobile competitor whose performance is well above other mobile graphics cards on the market. These are the only graphics cards that can really compete with high-end cards office, especially for models that ship two of these graphics cards in SLI and CrossFire. Unfortunately using the models are very expensive, DELL,Toshiba PA3817U-1BRSand Alienware (now a subsidiary of Dell) are the best known brands selling such laptops.

We advise you to read this table (English) for fairly detailed indications on the performance of mobile GPUs (it is updated continuously). But be aware that manufacturers are generally free to choose frequencies GPU from ATI and Nvidia, which has an impact on performance ...

1.3 Display:

Toshiba Satellite U405D SeriesLaptop screens are LCD type and it is difficult to know the type of tile used (quality is pretty good). There are screens of varying sizes from 10 "to 18" see 20 "in size 4/3 standard (very rare now) or more often 16/10, otherwise known as" wide. "On 16/10 close to the 16/9 is well suited for watching movies (no black bars as a 4/3) and for the office (larger screen). By cons, some older games do not support resolutions at the 16 / 10: the images displayed in resolutions 4/3 will be slightly distorted. Difficult to choose betweenToshiba Satellite U405D-S2848or the other formats, each with advantages and disadvantages depending on usage but 16/10 has become the standard.

The most common models are currently 15 "(or 15.4", 15.6 "wide in) for conventional portable. Much likeToshiba Satellite U405D-S2846flat screens office, these displays have a native resolution and the resolution change is not really possible because the fonts become blurred due to the interpolation. Do not hesitate to get in Fnac stores such Darty or to test the machine and see if the font size is convenient for you surfing or office in native resolution . screens current standards are:

The standard SXGA (Super eXtended Graphics Array) defines a resolution of 1280 x 1024 at 16 million colors. This method has the characteristic of having a ration of 5:4 unlike other modes (VGA, SVGA, XGA, UXGA).

The UXGA (Ultra eXtended Graphics Array) 1600 x 1200 with 16 million colors.

Mode WXGA (Wide eXtended Graphics Array) 1280 x 800 with 16 million colors.

Mode WSXGA (Wide Super eXtended Graphics Array) 1600 x 1024 with 16 million colors.

Mode WSXGA + (Wide Super eXtended Graphics Array +): 1680 x 1050 at 16 million colors.

Mode WUXGA (Wide Ultra eXtended Graphics Array) 1920 x 1200 with 16 million colors.

Mode QXGA (Quad eXtended Graphics Array) 2048 x 1536 with 16 million colors.

QSXGA mode (Quad Super eXtended Graphics Array) 2560 x 2048 with 16 million colors.

QUXGA mode (Quad Ultra eXtended Graphics Array) 3200 x 2400 with 16 million colors.

The tiles can be either matte or glossy (after treatment by the manufacturer). Shiny tiles are more common because this technique allows to bring out the colors, but in return, it makes the screen reflective, like glass. This treatment makes use of a very difficult screenshot bright outdoors or near a window lit by the sun. TheToshiba Satellite U405D-S2850matte screens are unfortunately increasingly rare.

2. Or buy his laptop and what brand to choose?

The brands that offer mobile services and quality (for affordability) that we recommend especially at this time are Asustek, MSI and Toshiba(Toshiba Satellite U405D-S2852). Brands Samsung and Sony are also interesting for their quality (and design) in the high-end and ultra-portable. Consumer brands such as HP and Dell(Dell XPS M1730 Battery), especially in the entry level are generally very good products at prices competitive enough. Dell is also essential in any price range, the robustness of the models is well established models of entry-level performance in both games.

We recommend fewer brands Packard Bell, Acer and Lenovo are very aggressive on price, but often at the expense of quality (cheap machines) rarely of the components which are the same for all laptops (Intel, AMD NVIDIA ...) but at the quality of the plastic hinges,Toshiba Satellite U405D-S2870power, finishing or the service (there are no secrets to offer prices as low ...). Some models very cheap Lenovo or Acer, however, can be adapted for some uses (internet, office, multimedia bit greedy) for reduced budgets. There is also the famous manufacturer Alienware (now a subsidiary of Dell), which offers high-performance machines and high-end prices actually quite reasonable considering the performance (a must for players demanding).

We often receive emails asking us to buy the best shops on the Internet. We do not pretend to know all of them but we particularly recommend the four following online shops: LDLC.com, Materiel.net, Fnac.com RueduCommerce.fr and their prices, their professionalism and the quality of their services . Darty.com, Grosbill.com and Topachat.com sites are also very recommendable.

The Dell laptopsPrecision M4400 Batteryare almost the only available on the manufacturer's website available by clicking on this link. Before ordering from Dell, we recommend you have a look at this forum topic that lists all the coupon codes that Dell offers every week. See our price comparison of laptops that references the most serious of the net merchants and compares the characteristics of several models in a few mouse clicks.

BuyingDell Studio 1737 Batteryon the net can often realize substantial savings and payment management / transport is now well settled, the potential problem of buying on the net is more in case of return or the service time can be a slightly longer (because of the travel time for the return). There is no fear with serious sites like materiel.net or LDLC. If you do not want to buyDell Studio 1735 Batteryonline, we recommend that you rather make your purchase from a specialty store or Fnac kind Darty (their websites are also very good, with the advantage of being able to move in a shop for servicing). Avoid general supermarkets which means often present at very variable and often (very) little benefit.

Stores (online or offline) sometimes offer warranty extensions (2 to 4 years), in the case of a high-end laptopDell Studio 1536that is not a bad idea because a laptop is still fragile, and the risk failure is especially important at the screen (some manufacturers offer warranties glass breakage free as Toshiba). Dell offers an extended warranty to 3 years for a relatively honest and quality of service is more recognized, Asus, MSI and Sony often offer a warranty of 2 years on their mobiles, an excellent thing that can tip the balance for theseDell XPS M1530 Batterymanufacturers.

Regarding the service, it is very difficult to know the quality of service in terms of brands, in general they are all pretty inefficient and very long: these services cost a lot of money to businesses (and their report anything directly ...). In the case of professional use highly dependent on theDell XPS M1330 Battery, it is advisable to take a professional guarantee to obtain a standard exchange throughout France and Europe in 24h or 48h. Dell offers such options ... but, obviously, it's very expensive.
