My son is looking for a point and shoot camera. Why oh why do they all have to be 10,12, or 15 Megapixels?! A point and shoot camera with a pinhole sized lens has no business having a sensor that big! This is one reason hard drives have to be so big.
I suspect this could have a profound effect on environments where salt and fresh water mix gradually and where the mix changes with tidal flow. I live in Virginia, and I can't imagine this would work without significant environmental challenges to the coastal waterways like those that flow into the Chesapeake Bay.
Ever notice how many times they were knocked on the head in every book?
