Powerful, useful and informative, but really only counts for those who are going to invest in the new software. I admit that I have not upgraded my office suit yet and so some of the items in the book were not applicable to me, however it does give me a sense of where the product is going and I can advise clients on upgrading and also next generation presentations. Powerpoint is THE tool of the presentation environment. Just plain fact. I could care less about the whys and etc, as what is important is that clients want PPT presentations plain and simple. This book lays out well the uses of the tool in how to lists and well appointed design.
For the office (not Office) professional who wants to go a step further for themselves or others (hint for a raise on that next review once you do a make over on the boss's next ppt will ya?); this will be a great addition.
Educators will want to get this book as a handy reference tool to point out some new features on the tool. Well priced.
