Aren’t the books you can buy for Kindle, Nook, etc just as expensive as real books?
For the most part, yes, although you’ll find public domain books almost free. They often knock a dollar or two off the price for a Kindle edition, but I’ve also seen some a dollar or two more. When the Kindle book is more expensive, there are often hundreds of outraged customers giving the book 1 star on Amazon. Looks like *they* are using the decreased manufacturing costs of an electronic book to increase profit margins.
