The first generation iPod Shuffle turns out to be an excellent accessory for the Chumby.  It fits well in the USB port with no need for cables.  If I use iTunes to give me, say 10Mb of data space, I can put my alarm1.mp3 and alarm2.mp3 in there for waking up to it, and then be able to play the music on the rest of the device.

Your mileage may vary.
