OS X is a cool, simple OS, but that's not my kinda OS.
What exactly do you mean by this? Do you mean that OSX's coolness is not cool enough for you? Do you mean that simple is not something you look for in an OS? Or what?
The concept, the power, and the look of OSX can whomp anything else I have seen hands down. The combination of *nix power under the hood with a beautiful gui that you can use or not use, depending on your preferences, is futuristic and useful. I think that OSX is perhaps the perfect operating system. Grandmas can use it, hackers who love vi can use it, toolsmiths who like to script everything with perl can use it, graphic artists can use it, and filmmakers can use it too. It's incredible in its versatility.
OSX's only problem, as far as I can see, is that it is under Apple's control. This has never actually affected me in any way, but I can see how it could. Apple can lock out certain protocols or take over certain protocols if they choose, and although it hasn't happened yet, it could.
Don't get me wrong, I like Linux too. But I think OSX is the perfect medium between Linux and Windows, and I wish more people had the chance to realize that, because it would change the way a lot of people think about Windows.
