I have wanted to try a matrix-style keyboard for a while. It seems like such an obvious improvement over the traditional design, I'm amazed there are not more products out there.
Looking at the 2020 and 2030, it seems the 2020 is actually the superior design. The separation between the hands is greater - I would be worried the 2030 would be too cramped!
Also, the 2020 has two separate space bars. I wonder if these can be set to perform different functions? It would seem such a waste to have different keys accessible for each thumb and then not use them for different functions... If this feature is supported I would certainly get the 2020 model, but I haven't read anything to that effect though.
Suggestions for improvement:
1. Increase the separation between two hands. Ideally, by having completely separate halves connected via a cable.
2. Allow the spacebar on each half to be settable as something else e.g backspace or shift.
Those two features would make it Typematrix a killer product!
