From what I've read, the new reflow option for PDF only changes the size of text, not images, so any "text images" won't be changed. Also the reflow only works on a per page basis, not on the document as a whole. Because of this, you can get a lot of "half pages" in your books. I just finished reading a Secure Adobe book that I checked out from my local library on line. Because of the above reasons, the formatting wasn't real pretty, but I'm not complaining because now I can download books from my library for free.
