In theory it seems that more competition should be good for prices, but not so far: everything I looked up is priced identically to the Kindle price.
That's because a lot of books are under the "Agency Model" where if you want to sell the books you may not mess with the price at all. You can't do sales on the books, etc. Amazon, B&N, Sony, and now Google are powerless to move prices on these books. Great for competition huh?
