A long time ago, I pre-ordered the Keyboardio Model 01, and I’d almost forgotten about it when it shipped a few months ago. I’ve been using it ever since. There are a lot of things to like about it; the firmware is open source, as are the schematics and CAD files. But most importantly, it’s a joy to type on.
Ergonomics I get quite serious pain from typing on regular keyboards, but I have also tried two different Kinesis models, to no avail.
