I think this takes our personal library into the ubiquitous cloud, which is great. But again, the key question is, will Google be able to integrate with existing eBooks like Kindle, Nook or Plastic Logic. That will be the one big thing that will determine their success...

Another cool feature I really like is the ability for small bookstores to create their own storefront. That is a smart move. By opening the cloud, they will capitalize on the marketplace created by someone else.
