I found a site describing Mac OS X:
Since I moved to Mac OS X, I have had a few discussions with people who are curious about Apple and Mac OS X, but have not used the platform. Often, what they think is a somewhat distorted, perhaps even incorrect version of the "truth": there are many areas in which they think the Mac is worse or better than it really is. Consider (with colloquialisms preserved):
Macs are good only for graphics/media work.
Macs suck for hackers.
There is very little software for the Mac.
Macs are overpriced/not worth the price.
Mac OS X is Unix.
Mac OS X is not Unix.
Mac OS X rocks. Linux is crap.
Mac OS X is crap. Linux rocks.
Some such curiosities and questions are addressed in this document.
