I was just thinking, the regular iPod, wheel and four buttons. You were always able to change songs (At least in a playlist) without taking it out of your pocket. Now with the proximity sensor, the screen turns off when it's in your pocket so you have to take it out and have people look at you (and say "OMG he has it!!") every time you change a song. Would remotes work in this case, or would all controls be turned off in your pocket? I know the headphone controls come in handy here, but still. I'll miss keeping it in there.
