Bests & Worsts Reviews from Amazon

Well this is a first for me. 25% through the book and the author is requesting a review on Amazon. So I'm giving a 25% review of 1 star (I know that's only 20% of 5 but it's the closest I can get). Honestly though, that just cheapened the entire experience. So what's my opinion of the book so far? Book illustrations are in black and white, but author references the color of certain sections in the illustration. I did jump forward to the software section. The iMindMap program for Android of not available. Since this book is printed on demand, l'm not sure why the author can't update it as things like that change.
