I have recently released the kinT replacement keyboard controller: https://twitter.com/zekjur/status/1281130647776608257
Why would you replace the controller? There are a couple of good reasons:
* to build or modify your own keyboard
* to work around bugs in the standard controller, like I did back in 2013: https://michael.stapelberg.ch/posts/2013-03-21-kinesis_custo...
* because you prefer to run open source software such as the QMK firmware (https://docs.qmk.fm/), even on your keyboard
Unfortunately you have to have them custom built or build one yourself, but there are sites that let you easily order one.
Here’s an example https://www.reddit.com/r/MechanicalKeyboards/comments/ak8d0m...
I can't deny that typing prose in Dvorak is extremely pleasant. But switching between Dvorak and qwerty (I often use others' computers) and between a regular keyboard and a Kinesis requires me to remember 4 different shortcuts sets for each program that I use.
If you are mostly a writer of prose, I recoomend the switch. But the ROI is not there for the jack-of-all-trades programmer.
Life is too short to forgo muscle memory.
I was doing lots of typing at the time and my first day learning Colmak, I was amazed that I'd been typing for hours and my fingers didn't hurt.
OS X, for example, can't use the foot pedal for "Shift" and apply it to the "A" that you hit on the keyboard if they are two different USB devices.
So, you may need a keyboard that the foot pedal plugs into in order to avoid this.
I understand the new fangled 2 comes with real switches for the F key strip?
