When you consider how far and over how low-bandwidth a link each bit of data must travel, a geek's first question should really be why it uses so many pixels, not so few. Another salient point is that pixel density/sensitivity aren't just a cost and time tradeoff, they are actually a direct technology tradeoff. Biger cells collect more photons and have less noise at higher effective sensitivities.
