As others have said, it's not just a question of going faster. It's a question of comfort and not having to fight things. Having an uncomfortable chair or dim / washed out / fuzzy screen is not going to change if your code is right or wrong, but it's something less that's bugging you. For the question at hand, I'm inclined to think that what matters most is not so much typing speed as typing accuracy. If I have to constantly go back and fix a typo it's a just a PITA. I'm by no means a fast typist, but I think I make fairly few errors. So whenever I have to use an unfamiliar keyboard, the biggest issue I have is mistyping things and having to constantly go back and fix them. Also, modifier keys not being where I expect them aggravates me to no end.
