I am hoping to take some video footage of typing on it in a bit...currently im too busy. I was surprised how comfortable it felt when I took positions...with wrist rests it would definitely be super comfortable and would get rid of any twisting of the wrists.
I keep wondering how comfortable it could be to mount a datahand in this fashion...the halves vertical and back to back (with a spacer)...perhaps in a V shape opening towards the user. But, I dont have a datahand, so i guess i will never know.
