I use a (variant of) the Dactyl too and it's been life changing for me. I've always struggled with RSI and used to only be able to code for an hour or 2 at a time, but these days can spend all day/night typing (with small breaks to stretch) without any issues at all. I 3D printed adapters for my chair arm rests so the keyboards sit at the front of each rest, right where my hands naturally want to be. I can then recline my chair a bit and type for hours without sitting forward/hunched over the desk.
