I use Dvorak, but it has nothing to do with statistics for me. When I switched to Dvorak, it felt more comfortable on my hands. My typing speed is essentially the exact same, for example, and I don’t think you could find a measurable difference depending on which I use. But qualitatively – it feels more comfortable.
Exactly the same here. Since I swipe type, I have to imagine that would be a nightmare on Dvorak with all the vowels clustered together.
