I used OS2 a lot, both version 2.1 and later Warp 3 back then. While it was really powerful (not to mention a lot more stable) compared to Windows 95, it was also heavier and slower. IBM advertised Warp 3 as something that could run in 4 MB or RAM; that was no different from Microsoft stating 20 years later that Vista could run in a half GB RAM. Yes, the system loads, but you sadly can't do much with it save for looking at the shiny icons and enjoying the sound of the hard drive constantly spinning. Unfortunately back then RAM modules were so expensive that being forced to upgrade to 8 MB to have an usable system would make a difference, so although once upgraded the RAM OS/2 could become a huge step forward from windows, most people simply wouldn't spent that money.
