re: Working abroad: Anybody done it, and where are the best spots?

I lived in Vienna for two years. It was rewarding, but also very challenging. Most people underestimate logistical issues like getting a Visa, setting up a bank account, and getting phone service. These things sound easy but sometimes they aren't as straightforward as they should be. Language issues are a constant feature of daily life. You think people will speak English but they don't quite as much as you think. You won't be able to read contracts, policies, menus, websites, etc. You will use Google Translate for every little thing.

That said -- lots of positives, too. I won't elaborate on those because they are pretty much what you imagine.
