Microsoft a déjà commencé à expédier les premières tablettes Surface aux Etats-Unis

This means you can pull the Surface across a table by its cover and still not have it detach, but then pick the combo up and remove the cover quickly with a quicker tug.

The Touch Cover keyboard is one of the most responsive ones we've ever used and when installed, turns the Surface into the quasi-laptop. (The Type cover is a little thicker, but uses real keyboard keys for more tactile feel when you type.)

The 720p HD front-facing camera is angled straight out, but the back panel camera (also 720p) is angled up 22 degrees to offset the angling caused by the kickstand. That way, you can capture whatever is behind the Surface when it is propped on a table or other horizontal surface. The angled camera lens also means that you'll have to tilt the tablet a bit if you want to take a handheld picture with the Surface.

However, when we hooked up an off the shelf micro-HDMI-to-HDMI cable to the Surface, we were able to hook up to and use a HDMI monitor without any issues. The Surface supports extending Windows RT to the external screen, as well as mirroring the tablet's screen on the external display. This means you can use the Surface in a dual-monitor configuration, just like a desktop or laptop.

Conclusion
In terms of its hardware and operating system, the Microsoft Surface with Windows RT is a very good product. It's very light, and powerful enough to run a version of Windows, so it's very attractive to Windows early adopters as well as business users who have plans to migrate to Windows 8. It's powerful enough to be a daily carry device for work, always with you on your commute across the state or across the country. It shares some programs and its main interface with Windows 8, which is a boon, provided you get used to using the new Windows UI. Users who haven't yet tried Windows 8 will have to get used to the new way of doing things, but since Microsoft has mandated that all new PCs come with either Windows 8 or Windows RT, you'll have to start using the new UI on new Windows PCs and tablets eventually.

So should you buy a Microsoft Surface instead of an iPad or Android tablet? If you use Microsoft Office for work or school, then it's a no-brainer: Get a Microsoft Surface (or one of the other upcoming Windows RT tablets). Even though Pages and QuickOffice are pretty good programs, you really can't beat a real copy of Office when your work is on the line. If you use Office programs constantly, the Surface is the tablet and laptop replacement your inner road warrior has been searching for. Discounting Office, the Windows Store's limited selection holds us back from giving the Surface an unequivocal recommendation, since the iTunes Store and the various Android stores have significantly more vast collections of apps. There's no doubt that the most popular apps will be ported over to Windows 8 and Windows RT, but when that will happen is still up in the air. If there's an app you can't possibly live without, then you should check if it's on the Windows Store before plunking down your money for the Surface. It's because of the limited selection in the Windows Store that we can't give the Microsoft Surface the tablet Editor's Choice over the Apple iPad or the Samsung Galaxy Note 10.1 $159.99 at Amazon Wireless. But we see the potential. If you're a tech pioneer or someone who appreciates well executed design, then you probably have already put the Microsoft Surface on order. In that case, enjoy.

it look more like a prop from the Avengers than one of the rounded tablets on the market right now.  
The Touch Cover keyboard is one of the most responsive ones we've ever used and when installed, turns the Surface into the quasi-laptop.

If you hold the bottom of the Surface about a half-inch from the magnetic latch on either cover, the built-in magnets complete the job automatically with a satisfying click. Like in Microsoft's videos

Though the magnetic latch is strong, it takes virtually no effort to remove the cover with a free hand.
you can hold the Surface by the cover while letting the tablet portion swing in midair, and the latch won't come free.  

The USB 2.0 port lets you use external peripherals like scanners, printers, keyboards, mice, and external hard drives.

While the Type Cover has actual tactile feel, the Touch Cover has better responsiveness.

YouTube videos looked fine on the Surface, even 720p HD videos. Some 1080p HD videos did stutter a bit, but that's okay, since they're being downscaled to 720p on the Surface's 1,366 by 768 screen anyway. We had some trouble reaching Flash-heavy sites like the video portions of Disney.go.com, but other sites like Starfall.com came up fine.

Playing music and games won't tax your eardrums too hard. The Surface's speakers play very softly, even at 100% volume.

On Rightware's Browsermark benchmark test, the Surface performed a bit slower than the New Apple iPad.
the Nexus 7 uses the Tegra 3 processor to great effect, and so does the Microsoft Surface.

More important is the Surface's battery rundown numbers, which are good. The Surface eked out 7 hours 45 minutes in our video rundown test.  
The iPad's battery rundown was more impressive at 10:54 on the test, but the iPad has a higher-capacity 42.5 WHr battery (compared with the Surface's 31.5 WHr battery). All in all, the Surface is pretty good and certainly powerful enough for day-to-day use.

In terms of its hardware and operating system, the Microsoft Surface with Windows RT is a very good product. It's very light, and powerful enough to run a version of Windows, so it's very attractive to Windows early adopters as well as business users who have plans to migrate to Windows 8. It's powerful enough to be a daily carry device for work, always with you on your commute across the state or across the country.

The Microsoft Surface with Windows RT bridges the distance between tablet and laptop for many users, particularly if you use the Web or Microsoft Office constantly. The Surface has very good hardware and some innovative design, but Microsoft Office RT is the killer app that comes to the Surface and makes it shine.

So should you buy a Microsoft Surface instead of an iPad or Android tablet? If you use Microsoft Office for work or school, then it's a no-brainer: Get a Microsoft Surface
