When I recently explained one of the many reasons why I prefer desktop Linux to Windows, even over my favorite desktop Windows, XP SP3, I got a lot of people telling me I was full of hooey because I barely even mentioned Mac OS X. Good enough, here's my take on Apple's Mac OS X.
First, I really like Mac OS X. I've liked it, in fact, since before there was a Mac OS X. So, with all that, why isn't Mac OS X my favorite operating system? Because, even though its family tree goes back to open-source BSD Unix and the Mach kernel, Mac OS X is a proprietary black box. I have some very good clues, because I've worked with the BSDs and Darwin, Max OS X's most immediate open-source ancestor, as to how it works, but I don't know that for sure and Apple is making sure that I never will know.
I'm sure for most of you that doesn't matter, but for me, I really need to know that if I have to get down and dirty with an operating system I can do so. On the more practical side, and here I know I have company, because Mac OS X is as proprietary as they come, it's almost impossible to run it on anything but official Apple hardware.
