Got both the Xbox and the Wii
And WE'VE switched off the Wii. The Xbox plays games (especialy Civilization Revolution - the Wii version is somewhat lacking...) and Divx and MP3s all very well. The Wii is a toy that gets played occasionally if we're drunk.
The Xbox is a bargain, has loads of games and is a great media centre. Of course it IS made by the evil Microsoft empire...
