I've been a touch typist since I was a boy, and a programmer for more than four decades (started out on teletypes), and I've never had any kind of hand or wrist problems with normal keyboards ever. I'm choosy when it comes to keyboards though, for where I do most of my programming. Never liked the clicky ones, but what one likes is individual choice. Looking at my hands as I write this, my wrists are not bent, or at least so little that I don't notice it. My hands are still in the normal touch type positions. Tried split keyboards (like so many other people did) but they don't do anything for me. "Normal" keyboards have the huge advantage that wherever I am (at customers, home, work, computer rooms, everywhere), there's a keyboard I can use.
