The ideas that we take for granted in today's computing landscape were once all original thoughts that somebody had to devise and implement out of nothing. Both Apple and Microsoft were pioneering companies in this space, but not all great ideas that stuck necessarily came from either company.

Best of frenemies

When word got out that Bill Gates had announced Windows for the first time at the Comdex trade show, Steve Jobs was furious and asked for a face-to-face meeting.

According to an account from Apple's designer of Macintosh system software, Andy Hertzfeld, Jobs "went ballistic" upon learning that Microsoft's new mouse-based system had made its debut.

The two companies had agreed a staggered release – with Windows only allowed to launch in 1983, a year after Mac. Because Mac had been delayed, and that possibility was never defined in their 1981 agreement, Microsoft was still within its rights to launch Windows.

Jobs felt this was a stolen idea anyway and that it represented a betrayal of a fragile partnership. In this meeting, Hertzfeld wrote, Gates simply pointed out the fundamental idea wasn't either of theirs – and that the terms of a 1981 agreement still held up.

North star

Gates' witty quote underlines the frosty relationship that he shared with Jobs throughout their careers, until they buried the hatchet a couple of decades later.

This conflict originated when Jobs recruited Microsoft to be the first software developer for the Macintosh. Both companies, at this point, had exposure to the ideas being developed at Xerox's Palo Alto Research Center (PARC) – especially the mouse-based system the company's engineers had refined. For instance, Xerox Star was a highly influential predecessor operating system.

Microsoft didn't shift a working version of Windows until almost two years later, and, according to Hertzfeld, it was just as crude as Jobs had predicted. When Microsoft launched a version of Windows in 1988 that Jobs deemed good enough, he sued Microsoft for copyright infringement but lost on a technicality.
