Powell's wouldn't sell it to me either, and that after wading through 2 pages of "if anything goes wrong downloading the adobe ebook you're screwed don't expect us to help you" type of warnings that required me to check on boxes that said things like "I read and understand I'll be screwed and I won't come crying to you to get my money back" and I still couldn't buy it! They want me to send them an email???
OK Industry, I'll take the hint, forget I want to buy the silly ebook!
I did find out why the book is only available in adobe reader: publisher is adobe! :
