I can't see how people think this'll be haptic. That demo in the video was was cool, but the guy doing the demo even said he though it was a year to twenty-four months away from market. And we don't have a clue what a screen like that means for battery life, do we? We all know by now that Apple will not compromise on battery life.
If they weren't focussed on the battery, we'd have LTE iPhones on the market already. Now we're supposed to believe iPad 3 will have a retina display, LTE, and a screen constantly generating a static charge strong enough to feel?
Nah. I'm not holding my breath.
