Lol, ebooks should have regional pricing like games. Buying these books means I will have to shell out 1/3rd of my total monthly income (student in a third-world country). Makes me wonder if there is a market for a paid service that can make copies of books available for a monthly rate (kind of like a paid ebook library with region locking and special format that can only be read by the app with a constant internet connection - Netflix for books if you will ). But I guess it would be hard to do because its just texts and if there was money in this, Amazon would have done it already.

Pick up a free trial at safaribooksonline / oreilly. Perhaps someone or your institution would sponsor a paid 50 usd per month account.

The author is very friendly and responsive. I'm sure he'll respond to your concerns if you reach out to him.

Ah, my comment was not particularly about this book. It was just a general assessment of how pricing may be a barrier for useful and practical books to a larger set of audience. And a little bit of thinking out loud if there was a viable solution to it.
