[Edit: All right, I did a very superficial digging, and didn't get an apples-to-apples comparison. But it said that OS/2 sold 2.5 million desktop and 340,000 server versions in 1996. Windows 3.1 sold over 3 million copies within the first three months of its release in 1992. So by 1996, OS/2 may have been more popular than Windows 3.1, because the Windows world had moved on to Win95.]
