I like your analogy but don't view it in the same way. Some people think Michael Jackson was weird, disturbing, all apparences and no substance. Yet there is no denying that he had a lot of talent and many loved his music. Some of his songs are classics. Also, he is 100% human.
In the same way, some people think that OSX is all apparences, no substance and not suited to anything serious. Yet many people love its polished interface and excellent hardware integration. Also it is 100% Unix and most open source software runs on it as well as under Linux.
