The big difference between the compes is not the resolution - it is the lens. Sony Ericsson K800 has autofocus lens, while Nokia N80 uses fixed focus with macro mode. Of course, the autofocus system is more advanced, but you pay for the perfectly focused photos with shutter delays. You may miss the action if you are not used to the autofocus delay. For example trying to capture running children can be a challenge because of the focusing lag. You can solve this problem in K800 by setting the focus to infinity. After doing this the camera in K800 behaves like fixed focus camera and you can capture the action better.
Nokia N80 - just press the shutter With autofocus camera you need to half press the shutter to get focus confirmation and then fully press to take the picture
Both cameras have rich sets of controls. You can set the pictures size, compression, white balance, flash mode. The exposure compensation is a lot more usable on K800 (by moving the joystick left or right) than on N80, where it is buried in a menu. Instead of implementing real manual controls the manufactures have chosen to use "scenes", called "shooting mode" in Nokia N80. You can select scenes like Portrait, Landscape, Sport or Night Portrait and the camera will hopefully adjust to the situation.

The digital cameras use the EXIF headers of JPG files for storing information about the capture. Apart for the time of photo, Nokia N80 stores only the flash mode and the white balance setting. The two Sony Ericsson models store more complete EXIF information, including the really useful ISO and shutter speed values. This data can tell you for example if your pictures are blurred because of wrong focus or low shutter speed.
