Hate the things, wouldn't ever buy one. Aside from getting a sample chapter in order to determine the formatting, look (it's shown on-line, not via whispernet) at the size of the download. If it's in the 400-700KB range, it's not in Topaz formatting. If they don't give you the size of the download, but only tell you how many pages there are, be very suspicious. And if you do get one by mistake, send it back so Amazon will get the feedback.
