Stereotypes don't pop out of nowhere, the fact is there are Mac users exactly like the stereotype suggests, otherwise there wouldn't be the stereotype.
You can thank Apple's marketing department for the self-righteous attitude and general ignorance that the stereotypical Apple user has.
Ah, but has the Apple marketing department succeeded in getting us to buy their products? Yup, 'tis true enough, they have. Seems to me, if Apple is successful at selling millions of iPhones, iPods, MacBooks and Desktops, then they are doing what is ABSOLUTELY required and demanded by the company and its shareholders.
I also think Jobs is quite good as the public face of Apple. After all, he should be proud as hell. He started a truly great American company, left it some time later, and revived it upon his return. His silly Feces eating grin at shareholder meetings is a tad irksome, but hell, in my book, he has the right to be proud of what he has done. He is indeed a true icon.
If you were a businessman that started a company, brand loyalty and the (apparently) absolute love for you as chairman or boss is something I would think is "a good thing," to quote my third favorite business person, Martha Stewart. If your marketing department can sell the products you make based upon the tone of the Oink rather than the quality of the pork, they are doing their job.
I agree with the point you make regarding stereotypes; they are stereotypes because there is a kernel of truth somewhere in the assessment.
Then again, there are millions of Apple users out there that likely do not care one bloody bit about the glamorous aspect of the product and they do not fit the stereotype. So perhaps the stereotype is simply a view of the undereducated that judges the whole bushel of apples by the few that insist that they are less wormy and much shinier and brighter than the fruit offered by Microsoft, while holding up a worm infested and brownish looking Mackintosh.
They can be quite insufferable, those Mac fanatics. But try suggesting that an Android phone is not as good as this or that, and the Android Fan Boys on this forum will choke you.
Seems to me there is a growing Ubuntu (SP, too lazy to google) fan base that decries anything but Ubuntu for no good reason.
