The iPod shuffle with headphones
Unlike it's larger cousins, but as predicted, the shuffle is based on a flash drive and comes in two models. A 0.5GB (120 song) model for $99, or 1GB (240 song) model for $149, and it's shipping today.
Update: The iPod shuffle is available in the UK for £69 for the 0.5GB model or £99 for the 1GB model, and again it's apparently shipping today.
Update: Russell Beattie has a good review of the iPod shuffle on his blog.
