Did you read the rest of the review? The original point was that the
pixel density figure provided in the specs database should not be
used as a predictor of image quality alone.

So lets draw a line. What pixel density, given current sensor
quality, what is the highest pixel density where you can stiil get
reasonably good images?

I'm not sure that the position of this limit has been definitively
defined yet. If you look at this thread from John Sheehy:

You will see a demonstration that the 1.97um pixels from a Panasonic
FZ40 outperform on an area for area basis the pixels from a Canon
40D. That's a pixel density of 26 MP/cm². If you made a FF sensor
form those pixels it would have 222MP, and you could extract a pretty
decent image from it.

Apologies, failed to spot the rhetorical question. Phil?
