As a gadget freak I think the iPhone is cool. Same for the new iPods. I just wonder how much of a market they can have though. Remember, there's no touch feedback from a flat touchscreen, so you have to at least occasionally glance at that iPod Touch to "home" yourself.

But I envision future touchscreens that incorporate piezo and related effects. Imagine that the edges of screen icons have 3d ridges raised automatically around them. Imagine force feedback from a touchscreen (!). I'm betting someone develops those. THAT will be something.
