> Often overlooked is that the main reason for switching to dvorak isn't speed for most users. The dvorak layout is layed out for minimal movement while maintaining a roughly even split between hands. This reduces strain on a typists hands and helps a great deal with comfort when typing for longer periods of time.
I may not type faster than if I had stuck with qwerty, but I definitely don't have the wrist problems I keep hearing coworkers complain about.
