So why is OS X better than other (*cough*Windows*cough) operating systems? Metaphors play a huge part -- when you use a Mac, you're not just browsing through files or using plugins, you're flipping through what look like album covers, or pulling up a "Dashboard." And everything is extremely intuitive -- it's clear upon first look at the screen what does what or where to find certain features of the operating system.
Every system has problems, and OS X is no exception. But using it day to day, OS X definitely gives out all kinds of "wait, it was that easy?" and "just works" moments. And that's why we're such big fans of it in the first place.
