- Everything seems to be reasonably reachable (maybe after remapping some keys).
- It’s curved.
- The left and right parts of the keyboard are completely separated, permitting to position the hands freely.
- Wireless operation.
- The mouse of course (even better: two mice!), no need to leave the keyboard to use it.
There may be some drawbacks:
- Stability of the keyboard(s) when typing.
- Mouse jitter when typing.
- Not possible to use on one’s lap.
KeyMouse is expensive, but its price is in the price range of other (mouseless) ergonomic keyboards, and the keyboard is still cheaper than a good chair or a good display.
