I switched to Dvorak about 27 years ago. And I switched back to Qwerty about 26.75 years ago. I got to the point where I could comfortably touch-type in Dvorak to about the same speed as I could Qwerty. While Dvorak was a slightly better layout ergonomically, it wasn't good enough to justify the frustration of switching to a computer that I didn't own at work. I've heard that some people can switch easily and touch-type on both layouts, but I couldn't.
I mean, switching to a non-owned computer will be frustrating when you're used to Dvorak, because you're used to a more ergonomical layout.
I touch-type both Colemak and Qwerty fine, but I still sigh a little internally any time I have to use the inferior layout for more than a few minutes.
