EDIT (2024-08-10T19:23Z): I should clarify that I am referring to the layout that you use for a physical computer keyboard, not a mobile/virtual keyboard.
I feel like there is going to be a disproportionate amount of people not using a standard qwerty keyboard that replies to this :)
I use qwerty on a standard 100% and another split 60%. I am trying to switch to ortholinear split Dvorak, but haven't been able to design a keyboard I am comfortable switching to full time. I would also need two of them, one for home, one for work.
