Mainframe terminals were nasty, I remember them. Similar high keys to recent keyboards that are so liked by gamers… but I get it. My dentist had a carpal tunnel that needed surgical procedure.
If I don’t use mouse all day my hands are pretty much all right.
Good mouse and keyboard is a key to productivity.
Everytime I see someone using touchpad I don't get it. My fingers would be on fire in 10 minutes. People don't know what they're getting themselves into.
Mainframe terminals seemed to have the keyboards at a very high angle. Maybe that was to simulate the key height differences on mechanical typewriter, but for a computer keyboard I prefer them to be as flat as possible. I have not had any problem with CT since using flat keyboards.
Carpal tunnel syndrome isn't exclusive to using a mouse. I dated a woman who had a severe case of it from using a mainframe terminal with no mouse.
