I find it kinda ironic to claim it was non-scalable in the same paragraph you yourself mention two different screen resolutions But the real context was not so much display sizes but display drivers. Windows 2.0 worked on CGA, EGA, VGA, Tandy and, if I remember correctly, Hercules graphics cards. Someone here claimed that porting the Sailfish UI to a tablet was a big job because of the drivers. Windows 2.0 demonstrated over 30 years ago that this is BS. Porting some underlying layers may have been affected by different hardware to some extent but not the UI.
