Sure it might be written for the technically inept. It might be light on content and what might be considered as quality research. It may even be wrong at points, but no matter what is wrong with it, it does represent more publicity aimed at the masses for alternative operating systems besides Microsoft Windows.
You don't need to convince geeks to use Linux or OSX, its the mums and dads, everyday people, that need to see that there are other viable options out there, and a comparison like this is a good way to build such awareness.

Surely this sort of publicity is worth a mention on slashdot.
