I've been a Mac user since 2004-ish, and the computer I owned before then wasn't powerful enough to run the current games at the time... so I gave up on the PC gaming thing. Consoles is easier to manage, I don't have to worry about failed installations, or watching out for viruses and stuff.

Of course Mac has become more of a gaming platform lately, but I just can't really bring myself to play games on my computer. My one exception is point and click adventure games. These kind of games are perfect for PC gaming, but anything that requires quick reactions or aiming, I'd rather do on a console.
