I've used Dvorak for the past 15 years. I have learned to touchtype qwerty at school and then regularly trained it for couple of years without much improvement at around 60wpm (yeah, I'm not very agile). Then one day I red a book (I believe it was Bill Gates "Business at the speed of thought") and decided to switch to Dvorak and use same methods I used to learn it at school. It took me a weekend and Monday but on Tuesday I was able to type Dvorak and couple of weeks later I plateaued at around 80wpm. What I like about Dvorak layout is not that I can type faster but the feeling.
