We just saw the Wall-E toy in action, and it's a pretty interesting toy (although not $190 worth of interesting). The best features include fully articulating tank treads, 10 motors, audio and vision sensors, remote control by both joystick and touchpad, individual shutters on each eye, and collision detection. Wall-E also has a "follow me" mode that'll allow a Wall-E to stick to a kid or dog and track it around the house. (We would have tried it out, but it was far too noisy and crowded at Maker Faire for Wall-E to track anything or anyone reliably.) [Maker Faire and Wall-E]
