@canion Yeah, maybe a little bit of kicking them when they're down. But how else would they be able to get ahead of Microsoft and Windows 98? 😄
@odd I think IBM stopped maintaining it in the early 2000s, although I do believe there were some things still using it until like the mid 2010s, like ATMs, and I think the New York Metro ticketing system (this is from memory so I could be wrong). There is ArcaOS, maintained by another company, which I think is based on OS/2. That's still being maintained.
