I used to get a numbness on the backs of my hands after a long day of coding. It scared me! Switched to Dvorak, the numbness vanished, and I've been happy with it ever since. This was back in '95 or so. If you're happy with your QWERTY keyboard, good. Nobody's going to take it away from you. But I was glad to have an alternative. P.S. Also back in the 90's, I ran a genetic programming experiment in which I tried to evolve a keyboard layout that minimized finger motion across a corpus of text. The best layouts all had the vowels on the home row under one hand and THNS on the home row under the other.
