Inevitably, when you're thinking about buying a new camera, it comes down to a horse race between two models. That's where a new site, Snapsort becomes invaluable. Just type in the names of your two finalists and let Snapsort provide you with an easy-to-read, highly useful, feature comparison.
It's also fun. I learned all sorts of interesting details about cameras I was curious about. The interface is clean. Performance is fast. Very nice.
