I use a keyboard. Its perfect.

And in 3d games, I'll use a keyboard + a microsoft intellimouse 2 optical or something or rather (5 buttons + scroll wheel). The best of all mice .

I tried using keyboard + voice before, but my voice recognition always wants to add a blasted space after everything I say, so JJ2 won't recognise a number with a space after it. Same with the "t" key. So if I do use voice recognition, I'd still have to type "t" to talk before I can speak a message for the computer to type out. It was a nice idea though. :P
