While full windows on an anemic processor with battery life does not impress me that much, check out the idea of putting an 'alternative' scrollpad on the sides of the keyboard. That sounds quite nifty, far better than stylus or finger-on-screen scrolling, and you don't need to switch grasp/hold from the typing position just to scroll.
