Market share blues (Microsoft), installed base hymn (Apple)
If you've ever felt you had to defend the Mac platform against some PC/Windows fanboy,
this interesting column gives you a lot of important information. Tidbits like if Apple sells one Mac, two Windows PCs aren't bought, because the Mac stays in use much longer. As long as Apple
doesn't increase its market share, this is no problem for Microsoft. But quite clearly, Apple
is increasing its market share ever since their switch to intel processors (plus the iPod's success). You'll have to scroll down a bit in the article for the Mac vs. Windows argument, but the other stuff is interesting to read as well.
