I just did a very quick image quality comparison between the Nokia N80 (left picture) and the Nokia N73 (right picture). Snapped one picture with each camera. Under quite poor conditions. Both are 3 megapixels.
For me it seems like the two biggest differences in addition to the form factor on these two phones are better image quality but no WLAN on the N73.
So what do you want – WLAN or high quality images? As usual, we want both. Good camera and WLAN…
