Yes it does, sis. I bought three PS2's and 1 Wii and got equal play time out of both. A console that breaks a lot, sells a lot.
You're trying to imply that Playstation 2's success was solely based on the fact that it broke alot. That's false. I know of the problems with the launch models and models that came shortly after that but those replacements alone would not make up even 25% of PS2 lifetime~ sales.
