Yeah, I would take the cd out for transport, I've had to take the case off of a cdrom to get a jammed cd out once. Discmans and car cd players are built to expect bumps and jumps nowadays. It probably costs more to implement though, but I would assume a game console would be moved around a lot while game play is going on. I used to do it all the time because game controllers didn't reach the couch or whatever.
