my 5 year old waterproof camera shoots lackluster stills and is limited to 640x480 vids. So your post got me shopping to see what's available. Your camera seems to rate high, and it has an interesting high-speed capability that let's you do slo-motion vids or stop action stills.
The comparison video in the following link is helpful. They're all pretty good and it's a tough choice but I think the Olympus TG-2 and Panasonic DMC-TS5A look the best.
