Many Mac users are power users that use to run Windows PCs.
I have noticed that many PC power users (on tech forums) tend to focus solely on what their machine can do while Mac users focus on how and what they can do on their machine.
The PC vs Mac debate can be funny, and there are fanboys on both side. But the trend I see as a PC and Mac guy is that there are many pretentious PC guys who constantly need to validate themselves.
100% true for me. I used to run linux full time (last 5-7 years at least). I would spend a lot of time working on my computers. I also had a gaming machine and I'd spend a lot of time working on that computer to tweak out every little thing.
Now I own a mac. I use it to get my work done. It is amazing. I've also converted at least 10 people including the developers on my team, my CIO, and a few other people in my IT department. Most of them were just like me and exclaimed "Wait, you mean it's like linux without all the bullshit? Count me in!"
Prior to my first macbook (which I actually bought to run linux) I would downplay mac's as computers for stupid people and didn't believe the OS to be a real useful system. I was a fool.
That said, I'll be going back to linux soon. I'm not a big fan of apple. I like OSX, but apple is really starting to get a bit too overbearing.
