If OSXZ does it a different way, good for them. I have never used an Apple, nor will I ever do that. Apple is, IMHO, even more eveil than MS because the 'appear' to be friendly. But they are not. When was the last time you saw a machine NOT from Apple running OSX? Thought so. MS lets the user choose the brand of machine at least, Apple does not. Apple is to the computing industry as Saddam was to the Iraqi people. If you don't do as I say, then screw you, forget it.
If Apple would let other companies make hardware that OSX could be run at, at least they would close in on MS when it comes to beeing evil.
Personally, I consider what Apple does as uninteresting since it can only run on very specific hardware. People who consider Apple to be their friend is even more brain washed than Windows people.
Stay way from Apple and don't let them influence you, they are worse than MS.
