I guess it depends on the game. I usually use a console but to a game, for example, like StarCraft I want a pc. However, the main reason I game on a console is because usually my computer will always lag and then I have to lower the graphics to crap. Plus just having a lot of games on my computer always slows it down even if I'm not playing a game.
GASP! I just had a flash of awesome. I also like a controller in my hand for the rumble feature. (I'm a loser. I know) They should make a rumble keyboard!.....jk
