Like Netflix and its monthly rental service that offers tens of thousands of streaming movies to consumers, Amazon is reportedly set to launch a similar service, but for books.
What would make sense to me would be one or two dollars to rent one title for a month. You can take a chance on tons of books without breaking the bank, but if for a while you don't rent any, you don't pay anything.
Oh, by the way, how come the Americans get streaming video as part of their Amazon Prime membership, but here in UK we don't? It's so typical, we don't get Netflix or Hulu either.
