When it comes to the PS3 and the Xbox, I do agree that they are both good consoles, but what helps me swing is the companies behind the consoles. Should I really get started on what kind of company Microsoft is and what kind of man Bill Gates is? I'm not one to support cocaine-infused capitalist fat cats, so my faith lies in Sony because I think they're trying to give more to gamers that Microsoft, who are purely interested in targeting causal gamers who will spew their money out to them.
Just my dodgy opinion
