Check out my edit.
What about Tokyo or Singapore? I've made a thorough list of cities I want to live in throughout my career - I know, I know. I've always wanted to live like my dad did; travelling to a new city every 3 - 6 years, learning new customs and languages, making use of the opportunities within emerging markets etc..
I can post my list if you want? (I have lists for literally everything it's insane)
