Sansa's Xpress USB-stick player is like what the first-gen iPod Shuffle should have been. There's 1GB of memory, a small (but EXISTENT) screen, playback controls, 15-hour battery life, and microSD expansion all for just $59.99. Not bad for a flash-player.
It's too bad the iPod Shuffle has already switched to a clip-on form factor, which is actually selling pretty damn well. If you're more into the thumb-drive shape and more worried about Rhapsody than iTunes interoperability, then this Sansa Xpress should be up your alley.
