The way the UX has three buttons (back, home, recent apps) on my android pisses me off when it is hidden, default. Tactile controls are never hidden, so I'ld prefer those navigation buttons to be physical.
At the same time, had to change the time on the lcd display on my car -- was hoping we were done with this twice-a-year change for daylight savings, but not yet. Anyway, it took under 20 seconds thanks to good design, with clear labels. I can't tell how many years prior I'ld have to try to remember ... is it that I press the Volume UP and the Tune dial at the same time to get the clock to change? Or was it both the Seek next and Seek previous buttons? Crap like that because there isn't the room to justify dedicated tactile buttons for the clock.
