It's just practice. The 360 controller is somewhat deisgned for FPS (with the success of Halo).
I personally wouldnt play on a PC anymore, its just too boring and dare I say it geeky, and Ive been playing FPSs since Wolf 3D, on PC. Halo really changed that for me, and COD4 has cemented it, its amazing, and I can play it on the big screen with surround sound on a comfy couch online with 0 lag, 0 driver hassles, 0 PC related errors. It just works, and it works well, and it's fun.
Not to hate on PCs, last FPS on PC I played was Half Life 2, and it owned believe me. But Live on the 360 just suits my lifestyle more.
You know you can hook up your PC to your TV right? I am assuming you've got a plasma.
I can Hook up my computer to the big screen + HD compatibility and better graphics.
Also, i barely ever get any lag and i am not even on the highest tier of the High speed i could get.
I am just saying i am a lot more comfortable with the keyboard and mouse than the controller. I'll leave consoles to sports games and racing and shit.
And i can't stress this enough on the PC everything looks sooo much better than any console ever will.
Just go and check out crysis. That game is just fucking amazing.
