Query: Not a very useful book for new features in CS

I am very disappointed with this book. This book does not list or highlight the new features being added to the Photoshop CS. Most of the centents are the same as "Photoshop 7 classroom in a book". If you want to learn the new features in the Photoshop CS, this is not the book for you.
