I backed the project. The book should arrive in 1 or 2 weeks. Haven't watched the review yet as I was planning to do a review myself and also don't wanna get spoiled in advance.
All I can say is that they put a lot of effort into it and this has been among those Kickstarter campaigns that have been incredibly well communicated and stayed on time.
The book arrived yesterday and I haven't been able to put it down, absolutely marvelous. It oozes quality, it is very up to date (till first quarter of 2017 I believe), it covers a lot of design principles, with clear examples and beautiful photographs, I love it. It is so great the book puts the "user" in the center. The interviews, at least the once I read so far, are very special. They are very detailed and some of them are deeply personal (Suzanne Ciani's for example).
I don't want to get into your way Paul. As I am lazy anyway, I won't say much more about the book
. One thing is sure, I will use the design principles the book covers to help me in selecting my next piece of hardware. All I can say, just buy it!
