I have my computers warning message set as "Danger, Will Robinson," but I really can't see the value in owning the full-sized robot.
I don't think I'd even go for Nova Robotics SAINT prototype "Johnny 5," my all time favorite robot. Sure, they make for the ultimate collector's piece, but they take up a lot of space and don't really do anything purposeful. You can't even play MP3's on it.
I'd much rather get one of those restored arcade machines like Pac-Man or Asteroids, the ones that also have Microsoft Windows installed and built-in MP3 players. Now, those are sweet.
