I can't believe some of the crap being spouted in this thread. It's hilarious.
The whole PC vs Console thing has beed done to death a mllion times, but here's what I have to say on the subject. They both have their strengths, certain games just work better on PC, and some things are better on the console. I have a 360 and a recently built good spec PC, and I play them both pretty much equally.
I love FPS's, driving sims, RTS etc on the PC, but there is nothing quite like kicking back on the sofa, firing up the 360, popping Gears Of War into the drive and seeing stunning graphics through 50" of HD goodness, and hearing bullets ricohet round the room through the 5.1 AV setup.
Talking of graphics, untill you see Gears Of War on a decent HD set you wont appreciate just how gob-shatteringly amazing it looks. And it runs beautifully smoothly too. It just shows what the 360 is capable of in the right hands, and there is nothing on the PC that comes close at the moment (although Crysis will change that

)
As for controls, I always shyed away from playing shooters on console, as I just couldn't get on with using sticks instead of mouse and k/b. However, because GoW is such an awesome game I stuck with it, and it suddenly clicked, I can now use the Console controller almost as intuitively as mouse/keyb. It just takes a bit of time, but honestly people once it 'clicks' the controller is fine for shooters.
I was a little dissapointed CoD 3 wasn't coming to PC, but now I'm over my 'FPS on console' phobia I'm definately going to pick it up.
Oh and MuSsEr, I think you'll find that the CoD 3 TV-ads actually use in game graphics from the 360 version.
