I used OS/2 on a 486DX-66 back in the day at home. I ran also ran it on a my first SMP system - Dual PPro (custom IBM build that did SMP - I worked there at the time and even wrote some code for it). It was rock solid for the most part. I still miss parts of the GUI - the ability to rip off a template for printer or a Doc, etc. There are still things that the latest OS just do not do well. Biggest issue was alway the single input queue issue in the GUI that could lock up the GUI but the system would just keep running.

Also Galactic Civilizations was a damn good game and only on OS/2 at the time -
