True, but your opportunity window for taking a better photograph is higher with a good camera that has a more forgiving "auto" mode and so on... like I said, I think that the 920 would be fine, but the quality is average, and way short of Nokia's best work.
I would take those two over any of the "major" blogs... those two are legit
The N8 has a bigger sensor, better jpeg processing (it seems), and probably better optics.
The essential part is that the N8 shoots @ 1.75 microns/pixel , the 920 is @ the "standard" 1.4 microns.. in fact, there is no other smartphone currently on sale that uses bigger pixels than the Nokia N8. Things are getting crazy lately.. those new 13Mpix sensors are dipping down to 1.1 micron pixels, just for the sake of the "megapixel" war.. its silly.
As soon as they published the white paper on the 920, I felt like it won't be very good... I just couldn't see how OIS would help with the quality, Yes.. it helps out by giving the opportunity to keep the shutter open for longer, but what do we do with all the noise that pours in with it ? The sensor simply can't accommodate for that, not at 1/3"
Here is the white paper on the 920:

The 808 .. that is a whole different story, Nokia solved a bunch of issues which have been a problem in the p&s imaging industry for years in a very elegant way, and on top of that they put the whole thing in a proper smartphone.
Here is the white paper on PureView PRO which is used in the 808.. its very informative:

I really hope they can properly port it to Windows NT one day.. hopefully soon.
