Drivers are definitely out. Some games are really iffy. Especially from the Win 9x era, where they’d do stupid things like look for a 9 in the version string of Windows, or get the amount of RAM as a 32 bit signed int, so refuses to install if you have 4GB RAM or more.
We had a lot of dodgy old DOS programs that were fine under Win98, but XP broke them.
“Oh man, I’d love to use Linux because then I wouldn’t have to have Edge installed!” - Nobody. Ever.
People use Windows because it comes with the PC and it runs all their shit (maybe except some yellowing-beige and blue scanner from 1997) with no fucking about needed. They were never incentivised to use Linux. They don’t know what an OS is, and more importantly, they don’t care.
Oh and UMD, but I don’t think “I want to watch a movie in poor quality on a tiny screen on a device that’ll probably run out of battery before the movie finishes” was a market anybody was really interested in.
I like Colm Meany, but every picture I’ve ever seen of him looks like somebody has Photoshopped his face to be slightly smaller, like the old Woll Smoth memes.
