Whats good about the ps3 compared to a 360?

the PS3 is a blu - ray player which mean that the games are in HD and it can play HD films unlike the Xbox, with the Xbox you have to pay a yearly fee to use the Xbox live and to play games with other people on the internet, unlike the PS3 which is free to use. Metal gear solid 4, Killzone, little big planet (which would be a great game for the wife) are all exclusive. the web browser is okay to use, i like going onto the PlayStation store and getting free demos. also with the PS3 when you buy a game, later on they will be upgrades for the game whether that means extra content or it fixes bugs in the game, im not sure if Xbox do that. due to the high cost of producing games now most developers tend to go for cross platform games to ensure that they can get a lot of profit back
