It's a looker and the upgrades are worth it for some people... if you like the iPod way of doing things, the nano is a very usable little package. And the fact that it looks gorgeous doesn't hurt either. Although a different experience from the second-gen iPod touch, launched concurrently, the 4th generation iPod nano is a serious entertainer in its own right, somehow packing more functionality than ever into an impossibly slender device.
