In low light conditions, to me iphone4 is superior. In normal light, N9 take better pictures for sure. I think we keep using iphone4 because it is more "reliable", even if the quality is not always the best of the two. Same for videos indoor : we shot two videos at a rock concert, low light condition again, and we see more details on the iphone 4 video, and furthermore the sound is better (not saturated). That does'nt really bother me anyway, when I bought an N9 I knew its camera was not that good, and I don't really need it. Edit : for the color saturation, you get a point. But as far as it's not too surrealistic and you can watch some of your party/holiday pictures, I don't mind. One may bother, but anyway you don't use your phone as a main camera for your best pictures. The phone is useful to capture some quick pictures for the moments you want to keep.
