Here's one: I think I may have realized why apple chose to recess the jack on the iphone. I was walking yesterday, listening to music, with my iphone in my front pocket and when I went to adjust the volume I instinctively braced my thumb against the headphone plug. Since the volume keys are hard to push, you need to brace the iphone on the opposite side to effectively lower or raise the volume. This is not necessary on the ipod because the volume is touch activated and on the front of the device. Hence, flush jack. I bet apple wasnt going to recess the jack until testers came back with bent jacks and it was cheaper to recess the jack than to order new, lower pressure switches (or redesign them, altogether). My prediction is that this is the last we'll see of the volume rocker as its currently designed, and also the last of recessed jacks.
