Did some searching before posting this. The only two options I saw were from Belkin. The standard AA pack and their newer rechargeable pack. I could have sworn that I saw a battery pack that uses like two double AA batteries that clips to the iPod mini to extend the playing time. Thought I saw it on the Apple site, but can't seem to find a mention there. My reason for the hunt is that I can get the older iPod mini through work at a price that tosses the 1gb Shuffle aside for the price at this time. * hours is enough for now, but there might be a time that I would like just a bit more time, and the accessory battery pack seems to fit that need. Anyone seen what I am trying to describe?
