With the small sensors on the point and shoot cameras and the high pixel count you end up with very small individual pixels. As it turns out even wide open these cameras are already diffraction limited and probably couldn't resolve more than 6 megapixels at best. Stop down the aperture at all and it only gets worse. Having 12 megapixels on a small camera with a small cheap lens is totally pointless IMO. You end up with bigger files that take up more space on your media but no more detail than you would have with a 6 megapixel sensor. Worse, there will be more noise too as each pixel is only getting a few photons of light.
