Apple OSX is not an open source product, else you losers would be cheering when China took a free copy of it and resold it as "Red Star" or something similar like they do with Linux. And of course, Apple's stock is blowing IBM out of the water the last year too, just like Microsoft has.
Again ignoring and misdirection when your point was shown false.
OS X (as a client) has a completely open source base with proprietary software on top. OS X Server has the same, but the tools and utilities that ship with it, and what comprise most the fact that it is the Server version, are open source.
Apple bet the farm on these technologies, and it has paid off.
