I think fanboys of all varieties would do well to stand back and ask themselves "why am I arguing so arduously for this?" It's not just games or systems, fanboys exist in all walks of life and are particularly bold on the internet. You have fans of teams and athletes going at it on ESPN.com, you have wrestling wars (I'm not sure how this has evolved since WWF/E absorbed everything, although I guess there's TNA to offer competition and non-wrestling alternatives like MMA), etc.
It's insane to be so inflamed over things so utterly trivial. It's as if some of these people's very lives are defined by their favored source of entertainment. Football, PlayStation, Halo, whatever it may be. It can't be physically healthy, for one. There have been studies linking the stresses of rabid sports fan-dom and an increased risk for heart attacks. How many people on the internet are just one more nerd-rage away from a coronary?
Lighten up, kids. Your console god is nothing more than a metal and plastic box that spins plastic discs of frivolity.
