I've been wondering this since the announcement. How many fingers will the new touchscreen support? The ipod/iphone only supports 5 fingers at a time, which is as many as you can fit on the screen. But with a 10 inch device, you can easily fit both hands on the screen at once. I'm remembering an old mockup of a "MacBook Touch" where they show garageband in piano mode, and the piano app for iphone would be amazing with all 10 fingers.
