I didn't know Android devices did this. Do they use the same Senseg technology that these rumors are saying will be in the new iPad? From what I've heard, it's not just that the screen vibrates when you touch it.
I don't think Apple would add this in if they couldn't make it awesome, or at least useful. And I had thought about the whole "And touch" thing in the tagline for this event, but I had no clue what they might have meant. Of course you touch an iPad. Why would they add it to the tagline if there wasn't something different about touching this iPad? Apple is far too meticulous for that.
