I've been waiting for the print version before diving in, so I'm excited to see it's now available. For what it's worth, I'd be willing to spend more money on an all-format package. I need to hold a book in my hand and not stare at an illuminated screen to absorb the material, but sometimes carry a big book around is not practical so having a Kindle copy is handy. A PDF copy is good for referencing stuff I've already read. Since the book is printed on-demand, such a package might not really be practical, but I thought I'd mention it.

Congrats on getting over the finish line, by the way. It's a huge accomplishment.
