What do MP3 players need to progress to? Well, according to Sony, it's not increased storage, better battery life or a better screen. It's an MP3 player that rolls around the floor, dancing to the music and moving its parts. It seems so obvious now...
It's got 2GB of flash memory as well as Bluetooth for streaming your music. The speakers are reputed to be of a surprising high quality. You can choreograph dances to specific songs, or alternatively, the Rolly will freestyle, which you can see a video of after the jump.
