Battle of e-readers shows Kindle books much cheaper than Nook, Sony


After reviewing various e-readers recently in one of our savings experiments, I thought I would compare the cost of a variety of books currently sold by the three dominant forces in the e-book field, Amazon (Kindle), Barnes & Noble (Nook), and the Reader Store, which sells books for the Sony Reader.

For this study, I chose the New York Times selection of the 10 best books of 2009; five fiction, five non-fiction. I avoided current bestsellers, since they are often subject to price wars and loss-leader pricing.
