I'm about 1/4 of the way through it. I enjoy it so far. My only criticism is that I wish it had something in the way of exercises. It's a lot of copying (typing) code and it explaining what the code is doing and the concepts behind what you've written. That's a good approach, but I enjoy thinking through things on my own a little as well then being told how the author would have done it and why. Otherwise very good!
