I have been interested in ergo keyboards, but never found anything that has worked good for me.Although, I think I have improved in "touch typping" / "right hand position".
I have used two ergo boards. Tried an X-bows,
Unfortunately the layout on this one did not work at all! The Esc key is too far away (I'm a Vim user), and the other keys commonly used in programming is too far away. Maybe the layout is better for ANSI, I don't know.
Then I tried this keyboard at work a couple of years ago,
The keyboard in itself was quite bad, but the layout was okay! I quite liked the split typing experience, it made my typing better. So even if people don't use it for ergonomics, it will help you improve your typing.
3D printed Dactyl manuform 5x6 with Zeal Zilents and in-switch LEDs (pure horror to wire that up)
Hehe, looks nice though! How is it to type on?
