Nah; XBox is widely realised to be the best Console in form of power - and Halo 2 is one of the few games to release that power in ways Playstation can't. It is after all the best Game in the World - and even better in Multiplayer because if you hate the Storyline you get around it.
The Internet Playstation Systems are pretty bad
The Live! Service is top quality.
