Again, this stupid notion that OSX is perfect for the "average Joe", whatever that means. Now I have to even read it on LWN. I think that is utter BS. OSX is good in a few respects and falls short in many others.
OSX "success"(6% marketshare) is mainly achieved by a very big marketing budget and to a much lesser extent by good/sexy hardware. Those are way more important than the OS, which people don't really care about as long as they can run the applications they need.
