I'm afraid I'm not sure about the PDF. It was available as a PDF in the Humble Bundle Make did a while back (it doesn't seem to be available now), and it might be available via PDF on Safari? http://shop.oreilly.com/product/0636920031246.do
I'm not sure Amazon do it though. If you've actually bought the book then I could send you the PDF that I have here?
