Funny how small pixels get such a bad rap. No one ever says "the optical perfection of such and such lens is actually a disadvantage, because you need higher shutter speed/smaller pixels/larger aperture/better focus/etc to to take advantage of it." But people make the exact same argument about small pixels all the time.

In theory, one could use high pixel density to do better post-processing. For example, if one is willing to deconvolve diffraction, I believe more resolution is always better.
