I was all excited to read a complete guide to my new S100. The text is fine and the explanations are very clear, but the pictures used as illustration are practically useless. There are fewer pictures than I would have expected, though that wasn't really an issue. The picture quality certainly was. To see them on the iPad screen you need to expand them. Under any magnification, the resolution is so poor as to make the picture useless as an example of what the author intends to show. In some cases, it's so bad that the icon he talks about is invisible with all the pixelation. I would return this book if it was possible.
Update:
Amazing Amazon! They immediately refunded my money, and I since went to Whiteknightexpress, (at the author's suggestion), and d/l'd the PDF to my PC and I'm now a happy camper, changing my rating to 4 stars. It would be 5, but being a visual type I like LOTS of pictures.
