One other problem with a Delaware corporation, specifically, is that if you're in California, you may be subject to their tax in addition to Delaware.
Also, one other point. Investors love Delaware corporations because they know them and also because they tend to be favorable to the investor. You probably want to read that last sentence again. Also I watched a presentation by some lawyers from Reed Smith who argued That California may actually be preferable to non-investors.
But the best piece of advice I can give you is to pick one and go forward quickly without dwelling too much.
