Apple Computer's lineup of iPods has long been king of the hill among digital music players, but a new generation of rivals aims to claim a bigger piece of the glory. Shown here is the iPod Nano, released in September 2005, which comes in 2GB and 4GB models, with prices starting at $199. It's also notable for its physical proportions: just a quarter-inch thick and 3.5 inches tall.
SanDisk Sansa e200
A distant second to Apple is SanDisk. The SanDisk Sansa e200, which starts at $199 for a 2GB version, and climbs to $299 for a 6GB version. All offer a color screen, an FM tuner and a MicroSD slot for expanding the amount of memory available.
