I think MS Windows didn’t really catch on in a big way until Windows 3.0 as I recall. That was the “no going back” moment.

You recall correctly. It was a sea change in terms of multi-processing and presentation graphics.
Before that it was nothing more than a slightly better version of the PET o/s (as far as look and feel).
The release of Windows 3.1 was the version which had PC users lining up at Egghead Software at the break of dawn to get a copy.
Wish I’d been able to buy stock then.
