you're a bit confused by Fuji's 2002 camera lineup, you're not alone.
As of this writing, Fuji has nine models. Hopefully the chart below
will clear things up:
Pros: Very good photo quality, Small, light body, Nice, easy to use interface, Improved FinePix Viewer software
Cons: Shutter lag, Plastic body feels cheap compared to competition, Playback mode just OK, Very few manual controls means hard to get the shot in low/difficult lighting, No sound/zoom in movie mode, No AF illuminator, Not a fan of xD memory card format
Summary: The FinePix A303 is Fuji's new sleek and stylish, 3-megapixel, entry-level digital camera for 2002. It's one of the slimmest and lightest digital cameras in this category and designed specifically for the first-time digital photographer.
