If you're as "extremely accurate" on 360 as you are on PC than you're probably pretty horrible with a mouse. I don't care who you are or what you think there's absolutely no way to get the accuracy, and consistency that a mouse enables you to have with a analog stick. Go watch some competitive PC gamers and take a note out of their book.
This whole FPS on PC thing, you're doing it wrong son.
thats your opinion
