I also liked the FiNCH for similar reasons, having all the control keys on the side of the device, and only having the letter keys on the front would allow for a full keyboard typing experience on the go (not as good as the Bubby for walking and typing, but for typing on some system like a tablet, or VR headset i could see it being very useful.

I have Corne split keyboard one at home but feel like i get "claw hands" after a few minutes because of the size.
