But also a fair amount less finger motion (I did test this to my own satisfaction some years ago) for a given set of text. And qualitatively, I do think that has translated into less wrist strain.

I’m not a particularly fast keyboardist, and I don’t particularly care about the speed differences of dvorak vs. qwerty. But, I do quite appreciate what I believe to be real ergonomic benefits.

My wife switched a few years ago and claims also improved wrist comfort.

But nobody would ever choose a dvorak keymap if they were solely interested in that 1-2% speed benefit (I don’t know where this number came from, but I no reason to doubt it).
