10 finger touch typing without looking at the keyboard which is what I did, is very different from using two fat thumbs on a phone where you are forced to look (at least for me) in order to have any chance of hitting the right keys. On a PC I never look at the keys because they are qwerty anyway. I just use a software setting in my OS to change it to Dvorak so I must be able to type without looking. On a keyboard my fingers just know what to push intuitively so I only need to think of a letter or word and my fingers just types it from muscle memory. This is what I mean when I say 0% transferable skills because the same muscle memory does not work on a phone anyway.
