Last year I switched from QWERTY to Dvorak. At the time I typed about 55-70 wpm, with 99-100% accuracy. Testing just now, I got 55 wpm, with 100% accuracy (but I did a lot of correcting) on Dvorak.
So, why Dvorak? Did I give into the hype that I would type faster, I wouldn’t get carpal tunnel, that I would suddenly be really really cool? (… I don’t think I’ve ever heard the last one.)
