I know some reviewers said it took them a few hours to get used to it. The only thing it took me a little while to get used to was making sure at least some of the flesh of my finger was pressing the button (ie. since it's not physical, it won't press if you use just your nail). The feeling it gives is very satisfying. I find myself doing things just to feel the feedback. The little areas around the OS where they incorporate a more general feedback sensation is nice as well. Subtle, informative, immersive. My only 'gotcha' moment was when I'd powered the phone off completely (trying to deal with a wonky App Store issue), forgot it was fully powered off instead of just 'sleeping', and tried to wake it up by pressing the home button. Since it's not physically a button, there was no tactile sensation, and since the phone was powered off, there was no haptic feedback, so it felt like I was pressing on a piece of hard glass. For a second I was ... "WTF IS GOING ON. WHY IS EVERYTHING BROKEN AND WHY IS THIS BUTTON JUST ACTING LIKE A SHEET OF GL.... oh." Then, I laughed, powered it on, and all was right in the world again.
