I've been using Windows 8 exclusively on one machine for the past few months. It grows on you. You do need to get used to the differences introduced by the "metro" interface. That's probably the biggest hurdle.
That said I haven't used this on a tablet or hybrid device yet. Apparently that's where Windows 8 shines. On a desktop PC there isn't as much of an advantage.
