"Supposing that the Surface Pro won't match up well against tablets, how will it compare against conventional Ultrabooks? Here's where Microsoft's hardware could show some real advantages. To start with, the Surface Pro would have the advantage of convertibility. It's a tablet when you need it to be one--and when you snap on one of the keyboard covers, it becomes a laptop that can take full advantage of Windows 8 with a touchscreen designed to interact with Metro apps. You'll also get digital ink support: Pen input can be convenient, and this will be part of Surface Pro, though Microsoft hasn't said yet whether the pen will be an included feature of the base-price model or an extra-cost option. At 10.6 inches, the display will be smaller than most Ultrabooks; for many people, however, the flexible design will justify that tradeoff." - Miguel Caetano from Bookmarklet
