Which of these four digital cameras would be best for me?

The best way is to go to a Best Buy or Circuit City or other store that has them on display. How the camera feels in your hands and pocket is part of the decision. Other than that, the newer the camera in general the faster it will take the photo. We have a newer Olympus and it takes photos at least twice as fast as our old digital camera. We decided against the EXLIM and Kodak based on online reviews and didn't even consider the Panasonic but I just checked Amazon and it seems to be well-reviewed and has better image stabilization than the Olympus. The Olympus also uses xD memory cards while the Panasonic uses more common (and higher capacity) SDHC cards. It's bigger than the Olympus but you'll have to hold each in your hand to make that decision.
