"Currently Unavailable. . . Sold out for holiday. Expected availability mid-January."
Mid-January, of course, is after the expected product announcements at MacWorld. There has been speculation about a smaller iPod shuffle or perhaps no iPod shuffle at all. In the meantime, you can still order the 512MB iPod shuffle from the Apple store. If you really want a 1GB version, you might still find one at online. My Simon found a few, but not the usual quotient, of online stores reporting availability, and several are up for auction on Ebay.
