The Nano Is so very sexy. I'm really enjoying it. 4gb is absolutely the right size for me. If anything, it is too much space. Really a beautiful little machine. I love getting gifts :-)
Good sound too, I think it uses the same sound chip as the shuffle, which I've commented on my blog about before. I did miss having a display on the shuffle, so this is just about perfect, and it fits in the strap of my backpack, like the shuffle did, so all is well in biking to work while listening to stuff land.
