But to be honest, it is broken. if you have an eink device with a 6" screen or even an iLiad with a larger screen, you can find some of the Mobipocket format books to be totally useless. Mobipocket is a format created originally for PDA sized screens. if you look at Mobi files that contain images, you will find most of the images are tiny. In some cases, too small to be of any use on a larger screen. If these images are important for the book you are trying to read, you will find the book to be useless in that case as the images will be small and possibly fuzzy. I've seen this problem and the thing to do is to purchase MS Reader format books with images and convert.
