Supprised no one mentioned Singapore yet. Lived there a couple of years. Huge tech and business scene in Asia, everyone speaks English, they welcome foreign talent, cheaper local food than most of western Europe, average residential Internet connection is about 7 times faster than the US according to speedtest.net, one page easy tax filing (no huge personal tax filing industry like H&R block), and you can rent a room in a shared appartment for around $400 per month. You also dont need a car and the typical doctor visit is much cheaper than the US. Singapore is like a well-oiled machine, clean and organized, a great feeling to be there. Worth checking out.
