Windows 8 is fine, _if_ you actually know how to use Windows. (Protip: Win-D takes you to the desktop from the app grid.) I would go so far as to say it's good, if you're using a touchscreen or tablet; the live tiles were useful.
Always amused me that the OS X Launchpad is also a ugly grid of huge app icons that takes up the entire screen, just like the Windows 8 start screen, yet nobody says a word about that.
