Excellent post by Thad this, read and think:
As you can see, Apple is missing half of the 10 titles on this week’s ebook bestseller lists (narrowed down to just self-published titles). That has to be troubling to Apple and its publishing partners. Apple and the big trade publishing houses could argue that the sorts of people who buy 99 cent ebooks aren’t iPad/iPhone owners. That would not be a clever argument. I would argue that after launching the iBookstore with great fanfare Apple is acting very much like a company that doesn’t much care about ebooks.
Barnes & Noble faces a different problem. None of the books here sells for over five bucks and yet Amazon manages to discount many of the titles from Barnes & Noble’s list prices, on average over a third off (of course it’s prices are lower still compared with Apple’s).
