What's the point of a PS3 vs Xbox poll on NGU? The majority of people on this forum is Sony fanboys, unless you are trying to find out what the majority of NGU'ers are using.
Post this on another forum like Se7ensins, or GDN, and the results will most likely be VERY different.
I have both systems myself, but I haven't been on my Playstation 3 in over 2 years now, because there is really no reason for it. Most games are cross-platform, most of my friends in real life owns an Xbox, and I happen to like the Xbox-exclusives like Halo, Fable and Gears of War a lot better.
