It's great for people wanting to learn some new things, but it always turns out that the code they created is actually the wrong and less efficient way to do things, so it's sort of like, as a reader, you keep asking, "Well why didn't we do that in the first place?" Then again, I already feel that way when I learn something new in CSC classes. Some things work better in certain cases, but in this book, nothing is the best way to do the thing until the book says so...until the next chapter, and the next.
It's also great if 40 pages of reading is intimidating. It's mostly stock photos and repeated code lines, so that's nice and easy to get through, I suppose.
