The best advice that non-photographers need to understand:
HOLD THE CAMERA STILL
It's especially true when a camera has a small lens. My Sony F828 was the largest non-SLR cameara when it came out, also at 8 MP. It's lens is nearly 15 times larger! There IS a difference in quality between two cameras of the same MP size. The best you can do to improve your picture quality is to minimize or eliminate vibrations, especially in low light.
