You've probably already bought your camera but for anyone else here's my two pennies worth...
I have always used Sony digital cameras, I think the 7 megapixel Sony DSC-W7 is the 5th I've owned and I'm extremely happy with it.
Check out the photo of Hong-Kong Harbour (reduced to 800x600, 80% quality)
Pros:
Menus easy to understand/navigate
Fully auto/semi-auto/programmable
Huge 2.5" screen
Fantastic picture quality with Carl Zeiss Lens
Good battery life (300 pictures no probs)
AA size rechargeable batteries, cheap to buy spares/use Alkalines in emergency
Sturdy construction
Ability to add Wide-angle/Zoom lenses/Filters (3rd party ones work too)
Ability to use underwater housing down to 40m/132ft
Cons:
Quite a bulky camera
Sony memory sticks are the most expensive £/Mb
Not infolithium battery so no "time remaining"
Small view finder
Accessories can be exensive (but at least they're available!)
Sony also make an otherwise identical 5 MP version (DSC-W5). The DSC-P200 seems to be basically the same kit (as the W7) housed in a smaller casing with smaller screen and infolithium battery. Perhaps more suitable if you want a truly pocket-sized camera, but no accessories (except perhaps a flash) are available for it as far as I'm aware.
