Personally, I use a Canon PowerShot S100 as a bring-everywhere camera. I upgraded from the S95 (which now lives in my wife's purse). My main criteria were getting the largest possible sensor in a camera size that could fit in a pocket (a regular shorts/pants pocket, not cargo pants or a coat), and the ability to shoot in RAW. That narrowed the field down to pretty much the camera I chose. I'm quite happy with the IQ of the S100.
