<mocking>I'm a Linux pussy who doesn't know what a real OS is</mocking>
Dude, piss off with your Linux bullshit.
I run a microkernel under the hood. I can run OS X and OS 9 side-by-side... yes... I can run TWO OSES SIMULTANEOUSLY in separate memory areas.
My OS has advanced features that come from a superior object-oriented design that comes from NeXTStep, with a heritage over 16 years old, using tried-and-true APIs and frameworks.
Guess what... OS X doesn't use the shitty ass graphics layer that you are a namesake of... that's right... X11, that outdated, outmoded piece of shit.
Real men use their computer to get work done, not to fuck around with shitty config files.
