Sony Rolly
Half Aibo, half iPod, the Sony Rolly ($450) is an MP3-player/robotic gadget that rolls around your room playing music from its two built-in 20mm active speakers. The music comes from either Rolly's 1GB of internal flash memory, or a Bluetooth A2DP/AVRCP enabled device. Features include a USB port, included Motion editor software, onboard ambient lights that display blue, orange, or green light depending on the music playing, and the ability to playback MP3, ATRAC, and AAC files.
