Am I the only one who prefers actual buttons? The best feature of the non-touchscreen iPods is the ability to perform actions without taking it out of your pocket. With a normal iPod, you can change the volume, skip tracks and fast forward or rewind without looking at it.
I really hope Apple doesn't milk the multitouch too much. It's very nice, but I don't think it's advancing usability at all.
I think that's is going to be THE hard decision for apple in the following years.. Make a full multitouch ipod nano, or stay with the buttons..
