I have a PS3 an had a 360. Both have there ups an downs. Ps3's downs? The cost, lack of games at the moment. 360's downs, sounds like a turbo jet ready to take off, has a high failure rate which Microsoft has yet to address. I am not a fan boy period that shit is dumb. I liked my 360 when i had it, good selection of games, was fun.
But I had ta get rid of it before the ring of death occurred! not just that but PS3 is getting alot of flack right now cause they are a lil slow out the gate but I think over all its gonna be the best system to have its potential hasn't even come close to being used yet. Anyway its really up to you an what you enjoy an can afford. cant afford $600 go with 360 its a good system i would buy an extended warranty though. if you can afford whatever go with PS3 its an awesome system as well.
