OS/2 Warp is still used today, albeit in very limited situations.

I managed IT at hospitals for a large part of my career. At one of them, they had a "Lanier transcription cluster". It was 6 systems. One of them was an OS/2 Warp install that managed the modem cards.

It's apparently used to manage hardware, like those modem cards. Evidently, it does a great job of it.

I agree with you though. I think that Open Source would have made it much more of a competitor to Windows, today.

Then again, throw enough resources at anything and it could contend...ok.. not TempleOS, but everything else. ;)
