I forgot to mention that the iPod touch 4G has terrible battery life compared to the NC. The iPhone might be better, but the touch has way too small of a battery. I'm not sure why Jobs wants to make the touch so thin that it has little battery life and is nearly impossible to hold unless you add a case to it, but he insisted they build it that way. I would have preferred fatter with larger battery. The NC battery will last around 8 hours or more, the touch perhaps 5 hours.
