I'm not much of a car guy, but I like my car just fine. Someone who's really into cars and has test-driven hundreds of them could probably point out dozens of deficiencies in my car and the way I drive it that I'm totally oblivious to. He might not like my car at all, but I'm happy with it and see no reason to 'upgrade' it.
Same goes for any other product field, hobby, interest, etc. People who are more interested are better acquainted with what's available and the way to get the best experience, and people who are less interested are happy enough with their point of view and oblivious to any short-comings.
