Video comment: I wanted to check how many simultaneous touches the iPad's screen supported, so I wrote some code to test it. Turns out that it supports eleven (11) simultaneous touches (the 12th won't register at all - I had to enlist Lauren's help to test that).
So, it really is an all-ten-fingers device, if you need that kind of input resolution. It also handles the visual touch-tracking pretty well, considering I didn't really try to optimise it at all. Each touch is shown by a small UIView, and the axial markers are drawn by the underlying primary view. Trivial, but kind of fun.
