I currently live in the Netherlands (always have), and I can't really think of a reason to leave, really. Sure, there are plenty of idiots here, but then again, you can find those types anywhere.
However, there are a few places that sound interesting to live, though they all have their downsides to. Austria and Germany sound really cool, though I'd have to miss out on even more fish. Iceland, Norway and Sweden all sound pretty cool as well, though I already hate the winters here, I probably won't stand the freezing cold and snow up there. California (and especially Silicon Valley) is up there as well, considering it still seems to be the place to be for anyone in IT. Japan's probably only a place I'd like to visit, as well as perhaps Australia, mainly just so I can eat a lot of strange things you'd never find here.
I doubt I'd ever want to live outside of the western world, though. Heck, a vacation still doesn't sound to appealing to me.
