I just saw one of these at BestBuy and immediately thought birthday present for Ian, my 4 1/2 year old (okay, so maybe it's for me, too :).

Over a foot tall, totally programmable, 67 pre-programmed functions, and a remote control, looks like the kind of robot most boys, and some adults, would love to have. Street Tech led me to a detailed review that includes hacks, pictures, a forum, and links to resources. According to the review, Robosapien can walk and pick up objects easily, but also performs a "roar, wolf whistle, the karate swings and chops and of course the dancing demo, where he will start playing a tune and dance around the place happy as Larry."
