I’ve found a very cool site: Keyboard Compare Applet for Dvorak and Qwerty Keyboards. The
Dvorak layout places the keys you most under the fingers best suited to use them.
Plugging the top 500 words from the english language into the applet came up with some interesting results: your fingers would have moved 72.09 meters if you used QWERTY, but only 42.44 meters with Dvorak. See the site for more details. If anyone is interested in switching and want’s some computer help feel free to contact me.
