I just bought this book two days ago and I'm loving it so far. Apart from the last few chapters that are now complete, you also get videos of Zed discussing the code and exercises. For the insane amount of work Zed's put in the material, I consider it a very worthwhile purchase. Given the tremendous amount of value I've derived from Zed's other free books, parting away with the $30 is the least I could do to support his efforts. Thanks Zed for this excellent resource!
