People who make up stories about Apple with no personal experience.
People who use long-obsolete faults to describe modern Apple products.
People who insist an Apple product can not do something it quite obviously does.
People who make opinions about Apple without knowing anything about the company beyond what they've heard others say--not even bothering to look for facts.

There are lots of Apple haters and it seems to me that the vast majority hate Apple simply because, in its difference, it has become successful. Rather than wondering why people would be willing to pay more for a product, they latch onto Steve Jobs' "Reality Distortion Field" and assume it's nothing but marketing--without even considering that, even with Steve Jobs dead and buried, more people are buying Apple products today than there were even last year. In other words, Apple haters are those who use nothing but emotion to validate their feelings for the company.
