I came to respect Unix systems, especially Linux, for years, but I could not escape Windows yet. I appreciate Richard Stallman and his philosophy, behind Gnu and Gnu license in many of its parts, tested several Linux distros, although Windows was still the primary os. After browsing the online Apple services, I was disappointed that they were not available for Linux. Also there were some proprietary Apple software that were OS X only, like Logic Pro, that I may acquire someday, without paying the price of a full Mac, only of Logic Pro. Mac OS X is not Linux, but it is Unix, so, less then Linux, better then Windows. There were also open source components in it and I did no liked that Apple was using open source for their benefits. Also I had more available apps to install, so I decided to give it a try, for those reasons: 1) Unix system, with larger app quantity then Linux; 2) OS X exclusive availability for Garageband and Logic Pro; 3) Lack of money; 4) As a statement of freedom, since I consider that part from the Eula that forbids installing it on non-Apple labeled hardware abusive and illegal, especially using open source components; 5) Because it is harder then installing Windows or Linux, and the result is really satisfying, once achieved. There are some drawbacks, like the fact that advanced GPU features are not available due to the old Nvidia Graphics, and booting with npci=0x3000 makes some things to just do not work, like many iTunes visualisations and new Windows software on Wine, but I think it is worth it.
