Going on a lengthy vacation, would you rather take:
A Kodak Easyshare Z712 7 megapixel?
or,
A Nikon Coolpix S3100 14 megapixel?
I own both of these cameras. Not particularly interested in buying another camera.
Observations on ownership:
1. The Kodak is easier to hold steady. The Kodak seems to have better glass clarity. The Kodak has a far superior zoom. The Kodak has a brighter flash if needed. The Kodak requires me to tote a battery charger along with it. It won't charge the battery via USB connection to a computer. The Kodak is heavier and bigger. Not a pocket camera.
2. The Nikon is easier to always have on person, being much smaller. The higher resolution can sometimes make up for the inferior zoom. However, this camera has a dull spot in every image taken. The Nikon will charge off of a USB connection to anything.
Granted, these pics are reduced rez hosted on Phototbucket, but you'll get an idea for each one with these.

Taken with the Nikon:
Every pic taken with the Nikon has that dark spot in the top right corner, in exactly the same place. No visible scratches or gunk on the lens to cause this.
I'm leaning far more towards the 7mp Kodak, despite its size and my limited cargo room. Mostly due to that spot defect.
