I covet the S400 version of this camera. I first ran into it at Keeble and Schchat in Palo Alto and I really liked the size and helt. O'Reilly has a good article about the family. I had picked up an S50 (in fashionable black), but it just is a bit too big. Takes great photos though, and when I bought it I got a terrific price for it.
update: Well, maybe the S500 or S300 is a better choice, the S400 is getting panned online for junky images and ccd bleed. I have to be disciplined and not buy a camera that doesn't match my size and weight requriements first.
