Review on David J. Perdue's NXT Inventor Guide

Desicritics.org, a blog run by Desis, has published a review of David J. Perdue's The Unofficial LEGO MINDSTORMS NXT Inventor's Guide. As a conclusion, they state that
"it's a book that makes you want to get off your chair and start building Lego inventions".Sounds rather positive, doesn't it?
All of you out there who have purchased that book: what is your attitude towards it?

In short, I think it's a great book to do after the tutorials in NXT-G. Tag-bot is so cute, we haven't been able to take it apart so I've had to buy a second NXT!

People should spend their money on this book if... they would like some post NXT-G tutorial help or ideas and building experience for different bots. Even fairly 'advanced' folks should find enough in this book to justify the price.
There are a lot of books that I could recommend...and this is one of them.

David's book is thorough and well-written. The instructions are the clearest I've yet seen.
This is an excellent book, especially for those new to the NXT.

what were the major points you were not satisfied with?
Being an author by myself, I know that authors always are grateful for constructive criticism, so they can learn from it and optimize these particular points next time.
