Did you learn something new from the book? Not really new and a lot of the book just goes around the same few points. The only thing that was different was the list of companies.
Was the book different from what you expected? Yes, I did not expect so many verified links and reviews about the companies that were listed.
Was the time period important? Time period is somewhat important because I'm not sure how relevant these companies will be in 5 to 10 years from now.
Disclosure: I received a review copy of this book from the author.
