The bottom line is: Save your money if you own the previous version of this book. Don't get me wrong, this book is a great book IF you don't own the previous version. If you want an update to CS, then this book does little more than repeat info from the user's manual. Scott does not seem to have any insight into using much of CS's new tools like RAW conversion or the Lens Blur filter. If you want to learn how to use the NEW tools in CS, wait for another book like "Real World Photoshop CS" to come out.
