I tend to buy my books in cash. That kind of settles immediately with the transfer of the note. Disputing a credit card charge for a card present charge with either a signature or a pin is much much harder than the typical internet "card not present" transaction, so #1 is sort of moot. Actually, in germany (and other parts of europe) it would be uncommon to pay a book with credit card, we all have debit cards that clear immediately. #2 just replaces the current system with the same system but another name and different actor, so I still don't get where the advantage lies :) I can totally see how bitcoin can work in online transactions where credit cards are currently used, especially if fulfillment happens after some delay, but I don't see it replacing cash unless we mint little bitcoins with an embedded chip that contains a non-removable amount of satoshis. But that's very much not viable.
