I've used Dvorak for ~10.5 years (currently on my MacBook, Model M, and Android) and I definitely don't regret it at all. Couldn't tell you my WPM offhand from either now or 10 years ago, but I type pretty quickly and have no issues touch typing. I might not necessarily recommend it to anyone else unless you're bored or have a good reason to invest in typing more quickly, but I don't recall the adjustment being very painful aside from a week or two of slow typing at the end of the summer break before my sophomore year of high school. The only real downside is that writing code on someone else's machine is a PITA. On the other hand, it's a good deterrent to others asking to borrow my laptop (no one ever does more than once).
