At the moment, i only own a pc. I want a 360 for sports games. For everything else, i use my pc (Driving with G25, FPS and COH)
A lot of console gamers perception of pc gaming is an image of someone sitting in an upstairs room hunched over a desk. It's what you make of it what counts. It doesn't have to be like that.
I have my nice big leather office chair and my nice big monitor on my nice big desk next to the sofa in the living room. The mrs can watch the telly, and i can play games. I get a shed load more enjoyment from being so close to the monitor, lights dimmed playing stalker, graphics cranked with good headphones and sound card than i ever would do from sitting 10 feet away on a console.
It's all about the immersion for me that makes me loyal to the pc. The sharp detailed graphics, top quality sound, G25 and a nice feeling M&KB.
