The 2001 date in the title is a guess based on the fact that it describes OS/2 1.3 in 1991 as "ten years ago", but I felt it important to include the date because a lot has happened to OS/2 since then!

eComStation came and went: https://en.wikipedia.org/wiki/EComStation

And today you can get a brand new and frequently-updated OS/2 in the form of Arca Noae's ArcaOS! https://www.arcanoae.com/arcaos/
