I have a keyboardio, which has a very radical split design with a function key that you hit with the part of the palm close to the base of the thumb (either hand). I think it's amazing, but there's definitely a learning curve. Not one to worry about for people that use a keyboard many hours a day. You just want to give yourself a ramp-up time, starting with a bit of usage, and building up to full-time use.
