This book covers everything you need to know without reading like a 1st grader's textbook. It also doesn't assume what you know or that you've ever used the previous versions of the software and covers the necessary points with the perfect amount of detail. I found the tips and tricks that are sprinkled throughout the chapter to be extremely helpful and I have a much better grasp of how to accomplish my goals when using any of CS5. I highly recommend this book- even a seasoned pro might discover some features that they weren't aware of.
