They don't type hard enough :-) Joke aside, I was mainly thinking about wrist problems. I think any normal sized, model-m layout or possibly split-layout keyboard with non-linear quality switches is ok. If the finger joints hurts, I suppose a lower activation force might be good - I guess one might be Cherry MX Brown, but I don't personally like anything else than buckling spring... The main message is that in my experience, laptops in your lap is the worst, and exercise helps.
