By far the best ergonomics advice I got was: do what feels natural to you. For me that’s a trackball, and home row typing with my lower arms resting on the table. I have had episodes where I was dangerously close to RSI, but after that last piece of advice those troubles were over. For a while, I stockpiled Trackman marble trackballs, but the MX ergo is finally a good successor. Split keyboards did not make that much difference. And watch out with weak laptop keyboards: if the keys go too easy, you increase muscle tension to avoid typos.
