I started using dvorak some years ago. I have since switched back. I don't think it helped my speed or my hands, and there were too many other costs which made it not worth while: having to set it up every time you reload your OS or start a VM, or change window managers, etc; it made the vi editor unusable, and while I mostly use emacs the ubiquity of vi makes it inevitable; using other computers in the lab became difficult, because they are shared with other people who used querty; it sometimes confused some programs and made them unusable; and so on. I don't think there is a long-term gain to be had. Read http://reason.com/archives/1996/06/01/typing-errors http://reason.com/archives/1996/06/01/typing-errors for an account of the qwerty myth.
