I'm personally pretty proud of the book. It's the first Drupal book by O'Reilly and the first to take a comprehensive look at building a "real" Drupal site with heavy emphasis on CCK, Views and the rest of drupal contrib.
I have to say, too, that O'Reilly was a lot of fun to work with. There's a reason they have a reputation for having the top tech books. If you missed it, @eaton and I did a live webcast with O'Reilly which was their biggest ever. Kool-aid for everyone!
If you don't have a copy yet, what's wrong with you? ;-)
