I have the s560 and love the features! I just got it last month, and took the book with me to Florida to read on the plane. - I couldn't believe all the things it could do! (And yes, I did read that it has sound.) I'm usually a person who doesn't like the initial change-over to a new piece of "techy stuff", but I found this one very intuitive. And I tried out a lot of the settings on vacation.
I was also worried about the switch from my old AA battery camera to this one having a rechargable, but I did find it lasted a long time. (I only had to charge it once while we were away.) - And it warns you when it gets lower, so you know a bit in advance. I still plan on getting a spare, but I'm glad I didn't let that stop me from choosing it.
I'm asking someone else to let the OP know how the prints come out, though, as we bought such a big card, and were so busy, that I haven't printed yet!
