I agree, touch feedback from a physical button is important. We lost that with touchscreens, I remember I used to be able to text without looking at my phone, not even at the screen, I used to be sure I pressed the correct buttons because of the feedback they give.

The same applies to music on my phone, I was able to change songs without checking on the screen where the "next" button is. I was an advocate of smartphones with hidden physical keyboards, but they didn't seem to catch up, not even with last blackberry's attempt, because they're not "cool" I guess...
