As I've been using Dvorak for the past 3.5 years, I've gotten the muscle memory down. The problem is with my job I have to set up a lot of PCs for people, people who don't use Dvorak. And it's been a bit challenging switching back and forth between QWERTY and Dvorak. This has led to QWERTY muscle re-memory creeping into my typing... at work. As a result, I've done my best to immediately open the settings and add Dvorak as a keyboard. It has helped, although I obviously still have to use QWERTY often. One thing I'll say is that on Win, the keyboard switcher doesn't maintain the selection when you tab to the password field, which is quite annoying.
