> And quite a bit of evidence that suggests that the "myth" arguments are recycled propaganda from a guy in the early twentieth century who had an axe to grind. Really? Where? (I'm not being sarcastic-- you are being specific enough that you clearly have something specific in mind.)
I'm not the poster above, but the best-known example of propagandizing about them is a paper called "The Fable of the Keys" by Liebowitz and Margolis ( http://www.utdallas.edu/~liebowit/keys1.html ), which dragged the Qwerty vs. Dvorak issue into the middle of an academic holy war about the free market. Much of the resulting Qwerty vs. Dvorak arguments have really been about economics , not their actual merits as key…
Anyway, I guess we agree. I find it plausible that Dvorak would be more efficient (I've even switched briefly before), but don't think there is any credible scientific evidence of it.
