Modern camera pixel density increasing?
Looking to find decent budget camera to replace my broken one. I'm noticing Pixel Density has increased since my Samsung S1050. It listed as 26 MP/cm^2, and took really nice shots at night -- I tend to photograph live music. I keep on looking at more recent cameras and am seeing much higher densities than that. In the past, anything over 30 MP/cm^2 seemed to not be able to get quality pics, but there's almost none of the recent cameras less than that, and I'm seeing what appears to be higher priced cameras going with densities above 40?!
What gives? Has the bar been raised such that 35 is the new 25 in terms of density? Or am I missing something, and the S1050 just had a very good color palette?

Yes, engineers are learning how to increase pixel density all the time. What you should be concerned with is how much noise is in the picture. These people do a good job of reviewing cameras, use them

I don't think high pixel density is a good selling point. Whatever, even if the technology advances applying that new technology to a larger area of sensor is going to give better results. Unfortunatly the ad men don't understand such things...
I guess part of the issue is, to keep the pixel counts high in new cameras the physical distance from the lens to the sensor array can't be shrunk much more, so on many new cameras the answer is (unfortunatly) to keep the physical dimensions of the array while increasing the pixel count.
