The new Nano has physical volume buttons. You can also slide your finger over the screen without looking at it, to select the previous or the next song. It looks like a very good and cool wearable media player, except that it does look overpriced. But I may buy one for cardio workouts, I just want to try it in a store before I buy. If it can stream music wirelessly to Apple TV, i will definitely buy it.In the past, a physical click wheel allowed users to guess the controls, adjust the volume, or jump a song forward or back. How do you do that with a touchscreen?
