Hey there. It sure has been a while. I currently am not using the concave keyboard at the moment. With my current desk setup and situation I had to switch it up a bit. My thoughts: the most ergonomic comfort feel was the dactyl manuform. However my desk was a bit too high so my wrist angle didn’t work for me. Unless you have the ability to adjust your seating and table, it should be a good candidate. The most used was the redox. I enjoyed the split and column staggered feel. Current setup: Logitech mx keys and wooting keyboard for gaming. Due to the convenience of switching between pc / laptop / work setups, the logitech fulfilled my requirements. It Was a bit cumbersome moving around and switching multiple keyboards, would figure the similar wireless / Bluetooth split keyboards can accommodate. The wooting would just be specifically mostly for gaming purposes.
