Notes v/s Exchange: Networking's 50 greatest arguments

Network World has an article on Networking's 50 Greatest Arguments. Interestingly (and as expected...), Microsoft is the subject of many arguments in the list, including Netware v/s Microsoft networking, Windows v/s OS/2, Microsoft v/s U.S. Justice Dept., IE v/s Netscape Navigator, Windows v/s Unix, Mac v/s PC, and the inevitable Lotus Notes v/s Microsoft Exchange.

Surprised to find no traces of Windows v/s Linux, BlackBerry v/s Windows Mobile, amongst others.
