I hate this question. I don't chose to game on any one specific system. Furthermore, all consoles and handhelds are nothing more than PC's with a different input and fixed hardware. So I say lets all forget this whole "I'm a Mac. And I'm a PC" crap. PC means personal computer. Therefore it is a computer that you use personally. A Mac is a PC. An Xbox 360 is a PC. A Playstation 3 is a PC. A Nintendo DS is a PC. A Nintendo Wii is a PC.
So aren't we all PC lovers?
