I just got a Nikon coolpix S3. It’s extremely small, and fairly capable compared to what I’m used to (the cheapest, zoom-less cameras on the market; this is the first half-decent camera I’ve had in my life).
I’ve got a Canon A620 7.1MP 4x zoom. It’s not ultra compact, but it’s not huge, and it has great image quality. It has a very nifty lcd screen that flips out and around (I think the S1 has that too?). I’ve taken portraits with it, and some very nice macro stuff too. It’s my “little Canon” for when I don’t want to break out my “big Canon” 😆
