Considering that I am not a very visual guy, but prefer logical arguments and hard, cold, numbers, you may be surprised that I found this book to be good!

It is a no-nonsense (well, a little bias is there in the book, that everybody is capable to draw graphics, which I can tell you is not true) book, which manages to be enjoyable after you have gotten used to the chaotic format and the plethora of illustrations in the book (too much illustrations, much of which doesn't lead forward, but just illustrations for illustrations sake).

Anyway, I believe that most of us can learn a lot from this book, and thereby be better presenters and have more productive meetings. In short, there is no catastrophic gaps you will have without reading it, but you will learn something if you decide to read it.
