Yes, it was a good run. Now I remember specifically: Started using the DOS version in 1990 in college. Bought version 3.1 in ~1992, Windows version running it under OS/2. Could afford to buy it then, even as a student. Ah, OS/2 was also good. It was < $100 for each version upgrade until 2000, when they switched to maintenance based licensing, soon bumping the price to $495. I had a home license which I dropped. I still had a work license, but then some sales twerp said I was using a pirated license at work, and wanted to speak to my IT department. This is a >100k employee company, so serious consequences for software piracy. I faxed them my valid license certificate, and told them to stuff it, dropping my renewal, and buying Mathematica. Now I see it's Mathcad Prime, a subscription based license, for $800 year. They were purchsed by PTC several years ago, which only made things worse. This is textbook case of screwing over your user base, cha$ing corporate accounts. I don't know anyone who uses it now. Many people used it back in the day. Sad thing is I don't even use Mathematica much. Too painfull most of the time. I don't like the interface, but it's better than browser based Jupyter. Just forget trying to install Jupyter and dependancies on a corporate managed Windows computer. I just use papaer and calculator. I swear things have regressed from 20 years ago. At least I can still buy a new RPN calculator.
