I have the keyboardio Atreus. It tooke me about a month to get back up to speed with qwerty. Did you learn colmak before hand or did you learn it on this keyboard?
I learned Colemak-DH on the side, practicing a little bit every day, until I got to about 40% my QWERTY speed. I had a Ferris Sweep split keyboard that I set up next to my QWERTY keyboard at work, and started using that more regularly. I soon switched to a split Corne full time before getting the Keyboardio Atreus, both of which are configured with the Colemak-DH layout.
This recent 62 key variant of the Atreus is an experiment to see how I feel about having a row of numbers.
Another row could be useful, but I thought the default layout of the keyboardio Atreus was clever because the second layer put the number keys right under the right hand so it worked like a number pad.
Another row for numbers would be useful for gaming though.
I’ve got the same Atreus. When I got it I realized the potential to move the keys around so a quick search led me to minimak. On realizing that just moving 4 or 6 keys could make such a huge difference because of how bad QWERTY really is….
That got me down the rabbit hole of layouts and I too settled on Coleman-DH. I still haven’t gotten entirely back up to speed, and I still make frequent mistakes. It was bad / hard enough that I actually gave up a few weeks ago and switched back to QWERTY; however it was so bad to type that way again that I switched back to Colemak-DH and it has been much easier the 2nd time.
