You should prove that OS X sucks in the first place. Or that Linux even comes close to Windows, let alone OS X.
What you just mentioned about OS X being easy is one reason OS X is much better than Linux. It's also based on an open source OS, like BSD, and runs most OSS applications available for Linux (and many more). Only the interface is not open source, and you can replace it. Furthermore, Apple is a leading innovator, and OS X gets many features that both Windoze and Linux only get years later.
I won't go into details, you'll just try to make a cheap imitation.
