Tiger vs. Longhorn
Yahoo!News takes a good look at what Apple and Microsoft have to offer in their upcoming OS releases (of course, Tiger is due out long before Longhorn).
Relations between the users of Apple and Microsoft computers have never been particularly cordial. Windows users claim they’ve won the war for the desktop: all you have to do is look at the numbers and you find the most of the world using a Microsoft OS. Mac users point out a near total lack of security problems, along with a bombproof operating system that never seems to crash. (Then they sneer at the Windows masses.)
Pretty good comparison of the two from a non-technical point of view.
