Wooooo. You must be young. Or new. Or something. This is what's known as a "console war" (even the the PCers are defining themselves as *not* console, but whatever). It's happened since the dawn of gaming (and I'm talking dawn, like, chess vs. checkers dawn), and it goes in all directions.
For instance, I'm a PC gamer. I own a (Windows) PC (by "a" I mean "three") and a Wii (mainly for my wife). Depending on the company I'm in, I can be:
1. A PC elitist
2. a corporate/Microsoft shill
3. Everything that's wrong with gaming
4. Not a "real" gamer because I don't use a "controller" (even though I have an XBox 360 controller for Windows that I use when I want to and "controller", as word, just means "input device", and what do you think a mouse and keyboard are?)
5. Pirate (even though I never pirate, there's often an assumption that all PC gamers are pirates)
6. A guy who plays games primarily on a PC and probably shouldn't be broadly stereotyped by that one minuscule fact because it means literally nothing regarding the rest of his personality. Seriously. You can make more accurate generalizations from what I eat than the fact that I game on a PC.
Anyway, this always happens at the end of a console cycle. The PC gamers get to feel superior because of the dated console tech, but in another year or so the next round of consoles will come out (WiiU's coming out this year, but it's not a powerful piece of hardware, so...) and console gamers will feel superior because everyone's catering to them again.
"It just goes round and round. Round and round and round."
