After quite a bit of internal debate I can not support giving a book a one star rating due to the price of the ebook. Stars and comments on a book on Amazon cover all forms of the book be it ebook, hard cover, paperback, or audio. While making a comment about a specific format may be valid I can not see ranking the book itself based on a specific format.
I vote with my pocketbook, I buy what I can afford. Just as I rarely purchased a hard bound book due to both its price and its physical volume I will not purchase an ebook that is too expensive and is DRM crippled. I'll wait for the mass market version and, more than likely, buy a used copy. Tough on the author but it is what I can afford.
BTW very cogent comment and summation Ken Irving, I hope you won't mind if I quote you.
