The human eye can detect photons hitting the retina, given a high enough quantity of photons. The source of the photon(s) can be infinitesimally small, as in a star many light-years away. This is not "seeing a photon" however. In order to be able to distinguish something from a different something sitting right next to it, you have to be able to resolve the somethings. Otherwise you are merely observing one somethings effect on the other somethings in its vicinity. Cramming more and smaller somethings into the vicinity will not change what your eye can discern.
None-the-less, it appears there is indeed a market of people who will buy 600dpi eReaders. And then 1200dpi after that. And on and on.
