Not much cheaper than a 1GB memory stick. There is a finite cost for the PCB, plastic housing, gold contacts, packaging, shipping, and other logistics. That is why you cannot buy small memory sticks any more, they can't make them cheap enough to be worth buying.
Both Smart Cards and Mag stripe cards (according to
http://java.sun.com/products/javacard/smartcards.html) have insufficient storage for books, and cost about $2 per card - I guess banks absorb this cost when they send you a new card, although these are all unique. Mass produced idenitcal smartcards in the same physical format, but with more storage might work for books, but the cost is probably higher than for the production of a p-book!
