The Surface's keyboard has a few more tricks up its sleeve. You can rest your hands on top of the keys, something you generally can't do with an onscreen keyboard. Microsoft invented a fast, pressure-sensitive digitizer that enables this feature; an algorithm helps determine whether you meant to press a key or not. Microsoft calls this feature "tap detection." One unanswered question: Will Touch Cover come with the basic Surface package or cost extra?
But wait, there's more: A second keyboard for fast touch-typists, or users who prefer the feel of tactile keys, will be available too. Called "Type Cover," it offers 1-millimeter key travel in an extremely thin package.
