It’s hard to be an underdog operating system when you’re produced by a Fortune 10 company. But somehow, OS/2, IBM’s heir apparent to MS-DOS and PC DOS, managed to be exactly that. It’s the operating system everyone who was around in the 90s heard of, but few understood. And it has a reputation for being something nobody used. So it surprises people sometimes that IBM ended sales of OS/2 in December 2005. Most people assume it was much earlier.
