Writing by hand is incredibly painful for me, and has been since I was a child. In college, I was diagnosed with a type of arthritis that resides in the hands. I used to dictate stories to friends to write down, but I avoided writing by hand in every way possible. When computers became accessible and the internet was available, I discovered a whole new freedom when it came to expressing myself, because I wasn't limited by handwriting anymore.
I know Kevin J. Anderson dictates many of his stories and a typist types them, so that would be a possibility, but I don't think I'd be a writer if I couldn't use a computer.
