There are the inherent "Mac user values" that are genuine part of the overall Mac experience, and then there is the shite people blithely put for the world to see on the intarwebs because arguing is easy, safe, fun and anonymous.
Yes, there are Mac users who have an irrational hatred of PCs, Windows, Ballmer, 2 button mice, etc. These are the sort of people who like to spout aformentioned shite on the internet, and they are tits.
Yes, there are PC users who do the opposite, they are equally absurd.
The above example are not examples of "Mac user values", just as they are not reflective of PC user values, but are more in line with just plain old Human values, many of which are selfish, uninformed and self centered.
The real Mac user values are by and large an eye for attention to detail, consistency, and elegance. This applies to the software and the hardware. It a mindset that says "that will do" is not good enough. One that does not merely see there phone/laptop/word processor etc as a means to an end, but as something that can and should be enjoyed whilst in use, not just endured.
The car example is a good analogy (although it breaks down if you push it too far...see what I did there...), and you can see the same arguments about the Mac/PC rivalry happening on motoring forums, whereby the ill thought but easy to spout brand hatred far outweighs any thoughtful commentary on the actual merits of the vehicles in question.
There are BMW drivers that are tits, because they only have one in order to show the world they don't drive common cars like a Focus. And there are BMW drivers who can genuinely appreciate the difference, and who drive one for better reasons.
But there's room in the world for both the "it will do, it's just a tool to get from A to B" and the "If I'm using it all day, I don't want to spend half my time cursing it" types.
And of course, there are more than 2 types, like me. I use a PC all day, and I get on well with it. It's like my work colleagues in a way, perfectly acceptable company for the daytime, but I probably wouldn't want to socialise with them all the time, for that I would rather be with my real friends who I can be more discerning about. So that's why even though I don't hate my PC at work, I'm glad to see my Mac when I get home. I drive my unnamed cheap foreign estate car to commute, and use my expensive british sports car for pleasure.
