Surely what you want is the best data about good places to start a company.

The real answer: it depends on your criteria. Delaware is the cheapest place to incorporate, but nobody knows where it is. Nevada is the best place if your business involves lots of cash and/or hookers. Silicon valley may still be the best if you want to meet like-minded geeks. Hollywood stays in LA both for the infrastructure and the weather. Michigan has great incentives right now if you don't mind the cold winters...see the problem?
