If you've ever tried gaming in dvorak, you'd understand why this is a good idea... Almost every game uses WASD or some other combination of keys based on the QWERTY layout, and the only game I've ever seen that actually uses window's layout is crysis, everything else assumes you're using QWERTY.. In fact some games, like Mirror's Edge, won't let you map keys to the comma key, making walking forward in the game impossible. I had to return Mirror's Edge to the store because the only way I could play it is to set my keyboard layout to QWERTY, reboot, play the game, set my keyboard back to dvorak, and reboot again.
