Good economy, but also good food which matters when you don’t plan to cook for yourself. Good transit infrastructure going anywhere you need or desire to go, so you don’t have to have a car.

Only thing it is really missing is the kind of critical mass of hackers that would make it into Y Combinator in City-State form.
