Sure, and when I attach a bluetooth keyboard - which is about once every 5 years, at this rate - I do specify Dvorak. Dvorak, as another commenter says, isn't as big a win for screen tapping. Dvorak does tend to alternate from one side to the other, but because the most common letters are on the home row, I'd expect it to encounter a lot of ambiguity in predictive swiping.
