Apple calls OS X “The most advanced operating system in the world,” but really they could have called it the most beautiful and few people would have objected. OS X is full of little design touches that have redefined what people expect from a personal computer, and which complement the gorgeous Jonathan Ive-designed Macs that it runs on perfectly. In fact, you can’t (legally) install the operating system on anything but a Mac, so the two are forever entwined – and that gives Apple advantages that other computer manufacturers simply don’t have. With Apple’s latest MacBook Air, for example, you’ll find special keys on the keyboard that link specifically to new functions in OS X Lion, such as Mission Control.
