I thoroughly enjoyed this program. It offers decision making, a wide range of skills and concepts, is presented in a very stimulating manner, and the options offered mean that it can be used effectively with a wide ability range.
It is indeed true that the scope covered by this book is very extensive, with a vast amount of information included, but I cannot really see the book appealing to a very large section of Electron owners.
The range of programs chosen, their comparative complexity and yet simplicity by virtue of the explanations, will make this book an interesting alternative for Electron owners. I found it quite fascinating to read.
