I have had the opportunity to play a bit with AIBO, when Ehud Sharlin came to give a talk at our CS Seminar. This little robot-dog was really impressive. Put some fur on it, and you might really get attached to it! Being a dog-lover, I can’t say it’s the same as the real thing. However, being an AI fan, I must say it’s really impressive and a real loss for the AI community.
