Tech betrayal No. 1: Et tu, Redmond?
When Microsoft agreed to develop a graphical user interface with IBM in 1985, the computing giant probably had no idea the software upstart was developing its own GUI to compete with it. But OS/2 flopped and Windows soared. When IBM and Microsoft severed their joint development agreement in 1991 there were 13 million copies of Windows 3.0 in the wild, versus 600,000 of OS/2. Companies that had bet the bank on developing for OS/2, like Lotus and WordPerfect, got their legs cut out from under them. By the time their products reached Windows they were late, buggy, and slow. Microsoft owned the desktop OS and, eventually, cornered the productivity software market as well, thus beginning its transition from spunky upstart to cutthroat monopoly.
