Editors' Note:*
Some of you may have noticed that in an earlier version of this story, we gave a slight edge to OS X. One of the primary factors behind this decision was the cost of each upgrade as it relates to licensing requirements. Although it is true that OS X lacks a feature like Windows XP's product activation that would bar you from installing it on more than on system, it is still a violation of Apple's end-user licensing agreement to install the upgrade on multiple systems. We regret any misleading information in the initial version, which has now been updated to clarify this issue.*

In other words the nicest thing we could say about OSX was that you could steal it :)

Seriously - the article is pretty amusing and as all such armchair analysis is it is just more fluff to grab hits. 

For me:  I LIKE OSX. if I had to run a Mac this is the OS I would run it on. It runs most Mac software and can run the BSD stuff if I re-compile it (though I am not sure how many variations of 'grep' I need) I Love XP and if I didn't already have PC hardware I'd switch to run it :)

Of course, I was amused that the considered emulators to be the same thing as "compatible" :)
