After the news of the ROKR I thought we were done. But then came the Nano.
Somewhere between a Shuffle and a Mini, the Nano is thinner than a pencil and doesn't have a hard drive (read: good battery life!). Available in 2GB (500 songs) and 4GB (1,000 songs), it has all the same features as the bigger iPod Photo. At 1.5 oz it's as light as two Shuffles. Best of all, it's available in black!
iTunes has also been updates to version 5 which includes a few new features.
