I switched to Mac a couple of years ago and am very happy with the platform. That said, reading morons on Digg makes me realize why Apple users have such a bad name. Vista is not nearly as bad as everyone makes it out to be, and I don't know why anybody would complain about XP - it's definitely more stable than Leopard in my experience.
Apple fans are summed up nicely in the Apple Product Lifecycle:
