It is painful to use Windows on my surface as a tablet, since I want the physical keyboard layout to be dvorak and the osk layout to be qwerty (because I've never really seen the dvorak layout). Microsoft obviously has no interest in making it accessible to dvorak users.

I think the dvorak equivalent of an osk is something more like MessageEase. If they would bother to update their Windows offering to something a little more recent (high dpi instead of scaling etc) it would be nice tho
