I think a big part of the appeal of Dvorak in the dev community is that there's something very satisfying about a keyboard based on real research. That research was done for 10 finger full-size keyboards though, and doesn't really map to the current generation of keyboards. As I allude to in that footnote, we've actually done some really cool research into optimal keyboard layouts in ambiguous scenarios. We'll probably do a follow up post diving into that! (also stay tuned, there should be a paper coming out soon).
