There are primarily 2 models
- KeyMouse Alpha → the whole left hand device works as a mouse, same for right hand.
- KeyMouse Track → with trackball instead.
It's expensive. $500 as of 2018-11-18
KeyMouse Comet, announced around 2019 March, but never in production as of 2020-05-08.
This doesn't seem like a good design.
When you have a symmetric keyboard, a lot nerds naturally think the center is the proper place to put the trackball. But that's actually a unnatural position with regards to hands.
The proper position for trackball, is actually near the thumb for a small trackball, or on the side for large trackball.
