OS X is just smooth, it just works, iOS and OS X devices just communicate with each other to print, share files, share video, etc. Everything is interconnected. There's a polished feel. Compare that to Windows 8, where you get this guy interface where everything get's a box no matter how insignificant it is and there's this jarring desktop that pops up when you run non-metro programs. Not that you can actually do anything with the desktop, mind you, except drop some shortcuts, but it's still there. The whole thing feels unwieldily.
