As person who lost the left index finger since 5 years old. I had been struggling with the non-sense qwerty layout that comes with every single laptop and standard keyboard, until I discovered I could have my own custom keyboard last year, it saved my career.
However, the laptop that I’m using for work doesn’t give me the option to use my thumb fingers in an effective way, other than hitting the space key.
It would be great having an option with an ortholinear custom keyboard with qmk firmware. A 46-key keyboard is more than sufficient for the majority of enthusiasts. The area of a 16" laptop should be enough to fit a 46-key Hillside splayed keyboard: Hillside 46
You’ll be able to reprogram the internal keyboard of FW16 because it will be using QMK firmware.
So even if it will be QWERTY it will at least be reprogrammable. It won’t make your thumb usable but at least you’ll be able to create some mappings for yourself.
