I have a nano 6G, and the current shuffle. I like the touch screen on the 6G, but wish it had the physical controls of the Shuffle. What if the Nano became circular ? The circle case would work as the classic controls, and the inside would be the touch screen. It would work quite well as a watch as well. Excuse my mock up skills, the circle controls should be smaller and the screen larger. Main problem with this would be wasted real estate a circular screen brings, for example if it was to show notification from the iPhone. Or still have it square, then add the buttons to the Nano black square perimeter.
