but I think if you look at the pics you wouldnt know it.
There are a lot more factors to the whole megapixle thing.
ESP for us here, we are not blowing up stuff AKA zooming in, too often.
Cameras use their pixels in different ways.
of course there is the normal parts of the camera (glass, apature... bla bla bla).
3 Meg + is fine long as you arnt doing poster work.
so
good camera at 3 meg > cruddy camera 5+ meg.
