I don't agree that it was "...a sophomoric and pathetic cry for attention".
I personally prefer the Mac OS to Linux as a desktop OS (yes, I've used Linux as a desktop once or twice) but I found the arguments in the article to be well-reasoned, if somewhat limited to the author's particular preferences.
Nowhere in the article did the author state that Macs and their users are dumb|useless|idiotic because of some feature (or lack of it). On the contrary, I thought that maybe there was a bit too much of the "for me, this is true" caveat in there.
My only criticism of the article is that perhaps it is a bit out-of-date. The critiques of Mac OS X are from an OLD version (10.2), so I found myself constantly wondering if the author would have found more|fewer problems with the current version or hardware.
My only suggestion to the author is to upgrade to an Intel-based Mac. Then you don't have to use a PPC version of Linux. ;)
