bad seed
I guess it's not really Sony's fault, but the lack of exclusive titles really killed it (especially combined with the crappy UI and inferior controller).

which isn't to say that it's a bad system, but I just felt no compulsion to buy one. there was one exclusive game on the PS3 that I wanted to play, and that's literally the only game I've played on it. otherwise, it just gets used as a blueray player and I play everything else on my 360
