This book does exactly what it says on the cover, and it does it extremely well. It has been my constant source of reference for the past three weeks as I have found even the often neglegted Index to be so well thought out.
I have always been a fan of the File Browser and was very sorry to see it be replaced by the Bridge and couldn't quite get my head around it. That is until this book came along. Ben goes through this, and everything else for that matter, in great simplistic detail and I now find it a breeze.
Everything new (including where some things have been moved to) in CS2 is covered in a very well explained and simplistic style accompanied by detailed illustrations. The presentation and layout of the book is absolutely superb, and for anyone making the move from CS to CS2 this must be at the top of their shopping list.
Remember though, it is a book for people familiar with Photoshop, not for someone coming in at CS2
