I've always had issues with the pay to be cool thing.
This tired old saw? Look, among any crowd, you're going to have a mix of motivations. Is it possible that some people bought Apples to be cool? Sure. Mum would say they have more money than brains.
In my professional experience, however, when given the choice of machine to use, 9 out of 10 folks chose a Mac. Why?
- Because it works, and it's one less thing to mess up your day - usually: every machine can suffer hardware faults;
- it has *NIX built in, so it's familiar if we're supporting Linux machines, but without the hassle of installing and managing Linux;
- and for me, personally, I prefer some of the tools available, like OmniFocus, that aren't available on other platforms.
So it's also possible that people buy Macs just because they prefer it over other options. Not every Mac user is an insufferable, pretentious jackass.
And that one guy who chose something other than a Mac? Yeah, he chose Linux, and then spent hours re-installing the OS every other week because he wanted the latest and greatest kernel, or he didn't like some kernel option, or he wanted to try Arch instead of Ubuntu, etc. He was weird like that.
To their thinking, this is strange and perplexing why anyone would want to leave MacOS.
I have a 2012 27" Intel iMac on which I installed Ubuntu, but that was entirely because I couldn't upgrade MacOS beyond whatever the last version was. Otherwise, I'd have been perpetually happy with MacOS. It's a fine machine, in all other respects.
To err is human, to forgive, beyond the scope of the Operating System.
