Has anyone used such a thing? I have been getting a persistent pain in my forearm that I think is due to too much scrolling? An large external trackpad with good software would be just the thing. Imagine hotspots around a page sized trackpad that would allow wheeless scrolling, a customisable launch area, natural hand action, true gestures (a-la Newton, PocketPC et al).
Am I dreaming? Oh, and in case you're thinking it, I didn't want to talk to Google, I wanted to talk to you.
