As a dvorak user, whatever increase in typing speed is mostly irrelevant, for most of us, our output isn't limited by how fast we can type, but how fast we can think. That being said, a long time ago I took an analysis of one of our code bases, mapped every character onto dvorak and qwerty keyboards to produce heatmaps, and it's startling how much less the fingers have to move on a dvorak keyboard. So if you're lazy, dvorak might be something to consider.
Overall, I've been using dvorak for >10 years and I like it. Going back to Qwerty is like going back to sleeping on a twin mattress. It gets the job done, but once you've become accustomed to sleeping on a queen, it's hard to justify going back to a twin.
