I don't know why Apple didn't make it possible to shop for books directly from iTunes, so I have a question for current iPad owners: are any of Terry Pratchett's books available in the iBookstore? The slide shown at the iPad announcement back in January listed Harper as one of the publishers Apple has on-board, so I'm hopeful.
And, while you're checking, what about Vince Flynn's books?
