Don't have a Kindle? Not to worry. Amazon's Kindle Reader application is available for downloading to your PC, Mac, and/or mobile device - all Whispersynced, so you can rent once, but read on all your gear, seamlessly.
Amazon is offering flexible rental periods: from 30 to 360 days, and if you need an extension - even if it's just a single day - you can purchase extra time.
E-textbook rental is not a new concept, but Amazon is hoping that the convenience of cloud note storage, Whispersync technology, flexible rental periods, and discount pricing on tens of thousands of titles will edge out competitors like Chegg. What do you think? Does this sound like a service you would try?
