Apparently someone has a superiority complex?
A few of O'Reilly's testimonies do give some concrete examples of user problems they had: "I refuse to spend weekends and late nights fiddling, Linux-hacker-style, with the scripts and codes and config files...". This sentiment reinforces that these users shouldn't have been using Linux in the first place.
It's thinking like that that makes no sense. What you are saying here is that only those people with the time and interest to learn complicated set ups should be the ones allowed to use a Unix OS? Pardon me, but setting a high barrier to entry like that is exactly why so many people *are* switching to Mac OS X, and if you don't like it, then you've got to be more friendly to the average person.
Sounds like someone here resents the fact that his 'superior' knowledge and skill (which really just means greater interest in operating systems and more time spent, not any actual brain superiority) isn't elevating him above the masses quite so high.
Forgive my hard words there, but flawed thinking does not give anyone the right to pass opinion off as fact. Mac OS X _is_ a Unix OS, but one where the traditional Unix barrier to use has been lowered. All the unix bits are still there for those who want them, and those who want them, will use them. It's a win-win. People who want Unix can have it, people who don't want to think about it don't. Either way, Mac OS X is a benefit to the rest of the Unix world, and that's an argument I will happily win, if you are interested in taking it up.
All of the above is solely my opinion, which I like to think of as firmly rooted in fact, but you're free to see things your own way.
