Apple iPod nano - Like a before and after picture, this updated iPod nano sports a slimmer, more attractive, all-alluminum body; as well as a 1.5" LCD thats 40% then before.

But if you need brains with your beauty, then Apple has you covered there as well. You get a new, higher capacity battery that can playback up to 24 hours of music, or 5 hours of photo slideshows.
The best part is, for about the same price of an older iPod nano, you're getting twice the capacity!
