I'd rather have a 5 megapixel f/1.8 than 12 megapixels.
I agree. Megapixel have become to cameras what power was tow stereo; a popular but pretty much useless specification for meaningful comparisons. Marketers love it because it is sounds impressive and makes for an easy comparison; even though a camera with more MPs may take worse pictures. Give me a better lens and larger sensor over more megapixels.
