Just out of curiosity, I was wondering if anyone out there ever used IBM's OS/2.
Back when Windows 3.1 was current, I bought OS/2 2.11 on floppies. If memory serves me, it was on 23 diskettes, including a Windows 3.1 installation (WIN-OS2).
I also used OS/2 Warp 3 for a while, and it was much easier to use than version 2.
After several years, I switched to Win95 because I started to write programs for a living and my employer used Windows.
I still have CDs for OS/2 Warp 4 and an install of it on Virtual PC for Windows.
