Agreed. For programmers, I would say the odds are good - you'll be doing a lot of typing, and RSI is a real concern. For people who do a lot of typing on other peoples' computers, planning around what's widely available (qwerty & vi on Unix, for example) is probably a better choice.

Good observation! Dvorak seems more clearly designed with touch-typing in mind, I think.

(As a data point: I type "wandering-hands" on Qwerty at 95-105 wpm, and about same on Dvorak. The typing isn't the bottleneck.)
