Don't be silly...it'll be iPhone HD
XL. You aren't keeping up on the rumors!
I wonder just how precise/sensitive such a technology could be. Braille might be a bit much to ask for. But it could be used to simulate the "click" of a real button, in place of the audible "tick,tick" sound it makes now as you are typing on the onscreen keyboard. It could allow you to not have to lift your finger completely off the screen as you move between keys, and though the tactile feedback you'd learn just how "hard" you have to press for the keystroke to register. (it'd have to have a pretty fast response time for this)
It could also be used for games where you have to pick up an object or move a widget into a bin, etc. Instead of a visible highlight on the screen to let you know when you crossed a boundry (ie, you are over the item/bin), it could be physical feedback.
Or how about being able to feel where the onscreen playback controls are so you can control your music without looking at the screen.
I'd be surprised if it could be used for precise controls, but something like the ridges you feel on a old-school iPod's click-wheel to know where you are on the controls should be possible.
