Polls like this don't prove which console is better, they just prove who in this group of people prefer or own more of each system.
EXACTLY.
I also have a PS3 and I use it to play stuff on my PSP like Infamous through remote-play (since it's hacked). It's very handy if you wanna play your PS3 games but someone else wants to watch TV or something. And I've never been a fan of the Xbox controller, it's very uncomfortable because one of the analog sticks are like on the top left of it. Very annoying after a little while.
BUT in my honest opinion, PC can beat any console, if you take out the factor of pricing. Isn't that mainly why people make consoles? So it's cheaper and nearly anyone can play games without buying a super computer?
