After thumbing through the book I decided to pick it up. I think the systems in the book are really interesting and I'm actually adapting them to my 4e game.
The book is chock full of fluffy stuff but stuff tied with mechanics so as a DM you get an idea of what type of rewards to apply to a player when they have a background or have own a business. The mass combat section is pretty neat as well, and with a little tweaking I can adapt that as well.
