"Apple is aggressively trying to break what it considers a dependence on software developers like Microsoft, Adobe, Quark, and others. Microsoft Office has been the only serious productivity suite for over a decade now. Office’s constituent apps—Word, Excel, PowerPoint—all enjoy better than 95% market share. There is no serious competition. Whether WordPerfect is better than Word or the late Adobe Persuasion was better than PowerPoint is a moot discussion; Microsoft won and owns the office productivity market on both Windows and Mac platforms."
Never having owned a Mac, I found this article to be a fascinating look at the state of Apple and it's platform. I find platform "soap operas" very interesting, and until reading this article I didn't fully understand the motivation behind Apple's move to develop so many applications in-house. This article might make some Mac users go berserk, but if you keep an open mind I think you'll find it's quite logical and balanced (at least from my point of view). It's a bit long, but worth the read!
