Tom's Hardware reviews the Surface

The guys at Tom's Hardware have played a lot with their Surface RT and here is what they said about it.

With the few things we dislike aside, we continue to be bullish about using Microsoft's Surface as a replacement for the Ultrabooks and MacBook Airs we carry around with us to trade shows and meetings, along with the tablets we use around the house when we get home. Flip the cover up and drag our fingers around the way we'd use a tablet? Sure. Drop the Type Cover down, snap out the kickstand, and bang out some email? Definitely. Hook up a second monitor for some extra workspace in the office? Yes, please! We certainly can't say the same for any iOS- or Android-based device.
One of the Surface's biggest advantages is its ability to multitask effectively. And yet one of its most glaring weaknesses is the Windows Store, with its limited selection of Windows RT-ready apps. We have to hesitate on a recommendation knowing the Surface Pro is coming soon. We're only afraid of what it's going to cost, given a steep price tag on a Surface with the Type Cover we like so much.

They ran a lot of battery tests and Surface's Battery is not bad.
