The MP issue just makes me gag.
I still have 2MP, 3.2MP, 6MP, and 12MP cameras. I have produced stunning 8x10 images from a 2MP camera. Lately I have been carrying the 3.2MP camera because it has wide angle capability. Anyone who tells you that you need 12MP to make good images is full of it. As has been previously stated, it is the qualilty of the lens and not the sensor that matters.
Many years ago, I took a photography class from a noted freelancer in the Detroit area, back in the film era. He told us that we had to shoot Kodachrome. Kodachrome does a nice job with skin tones, but I always liked the look of Ektachrome for landscapes. When we turned in our portfolios at the end, I compliments from him on my work. He never picked up on the fact that most of it was shot with the coarser grained Extachrome and not the finer grained Kodachrome.
Moral of the story, in case you missed it, is that it is all about the image and not the technology that you used to make the image.
