Amazon offering Kindle e-book rentals for textbooks

Just another outdated legacy industry being seriously disrupted:

Amazon claims students can save as much as 80% off textbook list prices by renting from the Kindle Store. The company is offering tens of thousands of textbooks, which students can rent for periods ranging from 30 to 360 days. Amazon has also extended its Whispersnyc technology so that students can access all their notes and highlighted content in the Amazon Cloud, even after the rental agreement is over.

Should you really need to buy an overpriced book to use for three months? This digital rental model makes a lot more sense. The big question will be execution and getting textbook makers on board.
