Well, I own the Xbox 360. On hindsight, I should have bought the PS3. Paying 50 € a year for being able to play games online seems kind of stupid, especially since it's free with the PS3. But then, you said you won't be playing online. Overall, Xbox 360 and PS3 are the same. If you're looking to play downloaded games, you should look for places that sell modded consoles that can play downloaded games. Just buy whichever is cheaper..
I will vote AMD for president next time if I'm having any shares during next meeting.
