I decided against pursuing this some time ago, but forgot to remove it. From what I’ve read it’s rare that a person can learn to touch-type in more than one layout. If you learn Dvorak, you’re likely to unlearn Qwerty, or have difficulty with it. I would still want to touch-type on other peoples’ computers and public computers, so I’m not going to bother. Also, the difficulty involved in changing some keyboards (laptops, the new Apple keyboards, etc.) to the Dvorak layout doesn’t seem worth it.
