Brother just came home with one, 4G Black.
Nothing too amazing, still just an iPod. 
Only thing interesting was how small the box was. His older one had a cube box size of a grapefruit; the Nano comes in a tiny box size of 2 CD cases stacked together.
(Heck, if I paid so much for a little tiny box, I’d be expecting ‘Tiffany Jewellers’ logo on it.)
