It's very true, but surely this 6-megapixel limit isn't fixed for all time? Things are going to improve, presumably. My more general suggestion is to find the latest, greatest number of megapixels in the newest point-and-shoot cameras, knock off about 30%, and buy a new camera with that many megapixels instead. A few years ago, I tried out one of the latest 6mp cameras, and was so disgusted by the image quality I returned it the next day to exchange for a much higher quality 4mp camera.
Coincidentally, I read something about this last night:
