I too received a copy and browsed through it. I'll give it a more detailed read in the next couple weeks. My first thoughts are that it's a great piece, not a complete how-to. It's laid out right in the front of the book to not take on more than you can honestly expect yourself to do.
I do not think a book like this can give every single reader everything they need to know to approach a project. BUT, the book along with other reference material, and input from others (yep even on this site) will assist many taking on a project.
For less that the cost of a tank of fuel, what's to lose?
