We are all clamoring for the supposed ipod updates sometime in september. Will it have GPS? Will it have 3G? Will it have a camera? Will it have external volume controls? Forget all that for a second, and let me ask you this: if there was a "redesign" of the touch, what cosmetic changes could be made? What would the touch LOOK like? To establish a few ground rules: camera/volume buttons/bigger screen do not count as cosmetic changes. Although these features affect the design of the touch, I am referring strictly to different materials/coloring/etc.
