I don't give a shit who you say uses a mac. OS X is built for retards. It is to prevent the average idiot (mac user) from tearing their system up because they don't have a clue what they are doing. These same morons buy their clothes from LL bean and drink $6 coffees. Windows is a superior operating system for every aspect of computing. It isn't hard to design an operating system for limited hardware. And as far as linux being developed on a mac, I laugh at that. Go check your sources and try again. Ask Grinch how many macs he is using at work. How the fuck are you going to write drivers for hardware that you can't actively test because your machine is some proprietary bullshit? you fan boys need to get your facts straight. Another thing, how much engineering (mechanical, civil, etc) is done on a mac? none would be my guess. I'm in civil engineering and I've yet to hear of anything for production on a macintosh. Oh yea, and FYI, OS X isn't linux. You have complete control over your system with linux. It might have a linux backbone because Apple is notorious for stealing other peoples shit then they cry and whine when someone does it to them.
