If the ebooks many want to read are expensive electronically, maybe many won't buy a kindle, but still buy the printed books ? And without a kindle, they won't buy cheaper books from the competition ? And maybe this will slow Amazon's success for a few profitable years, more profitable than current loses ? And maybe by that time the publishers will find an ebook strategy that will work(hard to believe, but maybe).
