I don't know that I would call it EDC, but I often carry a Pentax optio A10. I've had it for about a year, and so far I've been pretty happy with it. It is very small and takes good pictures, however, it sometimes had problems in low light situations. My cell phone also has a camera on it, but at only 640x480 res, it is barely worth having, but could do in a pinch.
