It's fairly obvious that they are suffering, why else would they now allow Windows to be installed on a Mac? Because Windows is more functional than OS X and people know that.
Finally, the makers of OS X, Apple, is an attempt at a monopoly over you once you buy their product. Mac this, iPoo that, with other OS's, you can get choose from a multitude of 3rd party addons or software that OS X can't compare to.
Most people complain about Other OS's problems, however these are usually because of carelessness and things THEY downloaded. When OS X crashes, it crashes.
Person B: "Because you got a virus. It' called W32.whatever."
Person A: "My Mac keeps crashing, why?"
Person B: "Because you got a virus. It's called OS X"
Irritating Fanboys and silly marketing campaigns (albeit now Microsoft have emulated them too- see the pattern here?) cloud its actual benefits, but its largely used for its creative capabilities. And when I say, "capabilities" I mean Logic and Final Cut work only on OS X, Industry-standard programs.
A 'true' user of OS X is generally quite irritated and bemused by fanboys and marketing campaigns and couldn't careless what OS you use or how much money he/she paid for it, because it works for them and they are rather pleased no one bothers making Virus' for their OS.
Microsoft Fanboy: "yeeeeah lololol youre sooo ghey I can play videogames lolo and DOS websites, gg n00b"
"True OS X user" : "So I've got a job and get laid regularly. Both of you Sod off"
Billy: Yeah right, you can't even maximize the fucking window.
