I gave my Canon Powershot S-30 to my daughter because I don't use it any longer - it's too big for a "shirt pocket".... So, now I have to get something really small, but that takes a decent photo, etc. My brother has a Pentax Optio S 5i, and says it does a good job. I'm also considering a Canon Elph. Nikon too has a slim one, the Coolpix S3. Does anyone have any comments, suggestions, or experience with one of these, or something similar?
