I presume you divided by 2.5 to get from 12MP to approx 5MP. However,
the pixel count scales with the surface area, which goes as the
square of the length.

Yeah, didn't occur to me until after I'd posted. Math is not intuitive for me. Still, it seems like an argument could be made for bigger sensors, bigger photosites even at the expense of resolution. Although some digiicams seem to be binning now. I assume that's why I keep seeing low-resolution/High-ISO modes popping up.
