It's called the "Ipod Shuffle." It costs $99 US for the 512 Meg model, $150 for the 1 gig model. It's ipod's new flash mp3 player.
It doesn't have any display. It plays all of your songs in different random order every time. Also, every time you hook it up to the USB port on your computer, it downloads a RANDOM set of songs onto it.
It sounds interesting, and it's the cheapest ipod there is now.
