Nothing beats a plug and play experience when you want to relax. Things screw up on PC and I never know if a given game is going to work. On console, I can buy a game on release and be guaranteed that I can finish it, and still be able to run all my old games as well without issue.
I've had driver updates break old games, break new games, your GPU choice can screw you over, and a whole bunch of other crap I don't want to even think about. I've been down that road.
I'll use PCs to emulate console games and enhance them with 3D support, high definition, etc, but I won't rely on it for enjoyment because I want a guaranteed-to-work system. Got kids and a job and no time to mess around.
