I can't see the point of apple putting all that effort into hardware for a tiny market. Particularly when anyone who wants an ebook reader, could use a product like ereader. It works fantastically on a macbook, I believe that apple may have released a new product recently and that ebook readers including ereader are available on it. While I can't imagine anyone buying an iphone to read books on it. Anyone with an iphone considering buying a kindle, should perhaps consider trying one of the free download ereaders first.
