I bought this book based on the stellar "Presentation Zen" by Garr Reynolds. (A must-read if you do presentations of any type).
What I was seeking to glean from this book was how to improve the look of my PowerPoint presentations. Though Robin doesn't cover this specifically, everything she writes about can be applied to the design of the slides.
The book is aimed at 'non-professional' designers. By this I mean those of us who design things in our work, but aren't trained to do so, e.g. flyers, event alerts, newsletters, reports, business cards, studies, articles, etc.
I found it funny how often she tells us not to be "wimps" in our design choices. I mean she REALLY tells us a lot. But her point is we need to be bold, not "wimps", in our design choices ... but only once we know the basics.
All in all an excellent read. Good examples, good overview at the end of each section, and good pop quizzes to make sure we were paying attention :-)
