It's not for me, it's a birthday present for my girlfriend, and she wants a PS2, not an X-box or Game Cube. I don't really know a lot because I've never been into gaming. If I buy it from Dixons or Amazon I might stretch to the 3 year extended guarantee in case she wrecks it. Then again, I spilt a pint of Draught Bass over my sisters one and it didn't damage it at all, just made it sticky!
Anyway, thanks for all the comments. The slimline one is meant to be quieter. Don't need to buy it for 6 weeks or so, but want to get it early in case shops sell out close to Xmas.
