I'm Jarrod, the guy behind Bootstrapping Design. Sorry I'm late to this thread, and thank you for sharing the book!

There are a couple of other design ebooks worth a look:

Sacha Greif's Step By Step UI Design: http://sachagreif.com/ebook/

Nathan Barry's ebooks: http://nathanbarry.com/app-design-handbook/ http://nathanbarry.com/webapps/
