Have you read the article in question? It does a pretty thorough job of analyzing (and demolishing) the "research" presented, by Dvorak, in favor of the Dvorak keyboard.
If anybody has a strong, data-based counter-argument in favor of Dvorak, I'd like to hear it.
There's a rebuttal here. I don't know if you'd consider it a "strong, data-based counter-argument", but then I don't think the Fables paper does a "pretty thorough job of analyzing (and demolishing) the "research" presented" either, rather it reads like the politically motivated hit piece that it almost certainly is.
I am aware of that. Can somebody please pinpoint the errors or show articles that explain where the writer has done errors? I am curious if it will be worth to switch, but I need some facts first :) .
As a very happy Dvorak-user I'd say "if it ain't broke, don't fix it". I switched because there was a compelling reason (repetitive strain injury). If you don't have a compelling reason, it's highly unlikely to be worth your time.
