Phone cameras have come a long way, but they still don't compare to point and shoot cameras. They are terrible in low light conditions (even cloudy days) and the zoom is a joke (digital, not optical).
I would stay away from Nikon, my family had 3 of them and 2 of them broke completely on their own. I then went to a Casio, and I am not thrilled with the picture quality. I would go Canon if it was me! Whatever you do, get one with a rechargeable battery.
