I'd agree that Lunduke seems like he thinks too highly of himself (if you've seen his self-aggrandising tales of his role at Microsoft you'll see what I mean), but I disagree with regards to the "Linux Sucks" videos.

Those videos don't really complain about Linux. The whole premise of that series is that he'll rubbish Linux for 30 minutes and then spend the next 30 minutes explaining why those deficiencies are actually great. It's a good premise, but most of the criticisms are quite shallow - it's mostly stand-up comedy rather than an informative show.
