you'd be surprised, PS2's are notorious for having problems with hardware failure when used a lot for DVD playback. Aside from that some people just don't want to have the PS2 and PS3 hooked up taking up space on the shelf and usually very valuable real estate in the surge protector.Originally Posted by zap'em up
Plus if they didn't have backward comp. in the PS2 to play PS games then to play all 3 you'd always need all 3 hooked up. It isn't needed but there's not arguement that it's nice to have and among video game consoles(since cart based ones) it seems to be pretty standard. If people weren't already used to having it they wouldn't expect it and therefore wouldn't care if it were there or not.
