Of course, Microsoft used DOS to push Windows and perhaps OS/2 was better in some ways, but the Wikipedia article suggests OS/2 lost because Windows was better in some important ways. The collaboration between IBM and Microsoft unraveled in 1990, between the releases of Windows 3.0 and OS/2 1.3. Initially, at least publicly, Microsoft continued to insist the future belonged to OS/2. Steve Ballmer of Microsoft even took to calling OS/2 "Windows Plus".[9] However, during this time, Windows 3.0 became a tremendous success, selling millions of copies in its first year.[10] Much of its success was because Windows 3.0 (along with MS-DOS) was bundled with most new computers.[11] OS/2, on the other hand, was only available as an expensive stand-alone software package. In addition, OS/2 lacked device drivers for many common devices such as printers, particularly non-IBM hardware.[12] Windows, on the other hand, supported a much larger variety of hardware. http://en.wikipedia.org/wiki/OS/2 http://en.wikipedia.org/wiki/OS/2 The other question to consider is why another PC OS didn't come up to compete with DOS/Windows considering that Microsoft actually helped open up the hardware ecosystem. A dominant player with most of the "market share" need not stop a new better player (see web search). Maybe it's worth acknowledging that making a good OS is a hard problem which MS cracked better than the rest.
