Please make the iPhone screen at least twice as large (4x6 good, 5x7.5 better), add a stylus, and come up with a name that doesn’t piss off Jobs by sounding too much like “tablet” or “Newton”. Maybe iSlab, iSurf, iCanHazTouchscreen, iFinallyhavethetechtomakethiswork; something like that.

Crank up the CPU a little, though, because I found Japanese text input rather sluggish on a friend’s original iPhone.
