Yes, I did attempt it after hearing the stories, but after a lifetime or so of perfecting my QWERTY skills it felt like a waste of investment. :)
Also, it messed up my muscle memory for EMACS keybindings (where the actual letters don't matter at all as much as the physical placement on the keyboard -- C-x and C-c are just too hard to reach on Dvorak), and it was hard for me to imagine that I could become significantly faster than I already am on QWERTY. Also, I do, after all, mainly type code, and since Dvorak is optimized for English, it didn't seem that it would offer much benefit to that.
In related news, my
favorite keyboard broke just this week. :(
