"Another thing I tried: the new home button, which uses a "taptic engine" to give you physical feedback when you press it — it's pressure sensitive too, so it can tell if you really mean to press it or just tap it. And it's awful. On a MacBook trackpad, you get this uncanny feeling that you're actually hitting a button. On the iPhone, the whole bottom of the phone just sort of "kicks." It's not bad haptics like you remember, with weird vibration, it's just a new kind of bad haptics. It doesn't feel like a button at all. It's a bummer."
