Hey, Right now I am using a Sony Cyber-Shot DSC-W200, but eventually I would like to buy a Digital SLR camera (most likely the Nikon D40). I have a quick question about the megapixel difference between my current camera, and the Nikon D40. The Sony camera has 12.1 mega pixels, but the Nikon D40 only has 6.1 mega pixels. I also understand that there is a Nikon D40X which features 10.2 mega pixels, as opposed to 6.1. How big of a difference will I see in image quality between the two cameras?
