Maybe I misread originally, but I didn't expect to have to buy a new ebook to go from 1.5 -> 1.6.
I understand why the authors have decided to produce a new* book, but I don't think they've thought about the emotional impact from a customer's perspective.

Basically, the book is now 1.5x the size as it was before. To me, this totally justifies releasing a new book. Having taken a chance on the early release of the original book and having my mind blown, I give these guys the benefit of the doubt.
My biggest disappointment is the lack of eBook. That's how I read the first version, and that's how I would read this version. I'd be glad to pay the price for a physical book, but I definitely want to actually read it electronically.
