In this article about Bill Gates' transition, we find this gem:
For much of Microsoft's existence, its two biggest money-makers, Windows and Office, have been firmly rooted on the PC desktop, where they enjoyed little meaningful competition.
Wow. Someone hasn't been paying attention for two decades. I'm sure that IBM, Novell, Sun, Apple, Mozilla, Netscape, AOL, Lotus, Real, WordPerfect, Digital Research, Ashton-Tate, Borland and the various companies that sell and support Linux don't appreciate being called "little meaningful competition."
Definitely one of the interesting things about working at Microsoft is that we have always had very strong, talented, and determined competitors.
The other interesting thing is that we're apparently always about to be finally beaten by another company. In fact, I'm sure there's an article to be found somewhere out there for each company above that assures its readers that the company has beaten Microsoft.
