An article about a rumour of an Apple product feature. Hmm, slow news day?
As for "push back",isn't that just a fancy vibrate motion like when you type on a smartphone and the internal vibrator motor makes the device shake a little?
I do wish more tablet makers put the little vibrator motor in theirs, it almost makes typing on a touchscreen keyboard bearable. I also wish said tablet makers put a big fat white LED next to the camera too.
