The pdf is nice and all but perhaps using an epub file format instead of an ibook format would have been nicer and more open.

Edit: Never mind. It was a stupid suggestion. The pdf is just fine. Can't believe I had a moment of iPad jealousy.

Not the UK itunes store :( I know I could make a US account but..

Well, that is unfortunate. At least you can just get the PDF or try contacting Dr. Stanton.
