Regardless, 2 thumbs are very different from all 10 fingers. Not the same memory. When I touched typed Qwerty, reaching the "O" meant straightening the right ring finger. On a phone, this means placing the right thumb somewhere. Very different. Though I didn't realised how dissociated those could be before I used my Dvorak-like layout.
