Ok, here's my feedback.

Caveats - this is my first digital P&S, and my first underwater camera.... although I have now about 8 months experience with the 10D, and before that about 10 years using an EOS 100, so I know a little about the principles of surface photography... but I'm no pro!
Regarding various questions:
- you CAN use the flash underwater
- you CAN turn it 'off' once it's popped up, but only in a couple of the 'image' modes (e.g. 'fast action' mode, with the icon of the sprinter on the mode dial). In P mode, you CANNOT turn off the flash. (well, I can't find a way, short of pushing the flash down... not an option once under water.
Pro's:
- all the buttons work under water.
- unit is 'slightly' positively buoyant... it bobs nicely around my head when I'm not using it, but you'd need to watch it on swim-throughs
- o ring is easy to remove & grease
- glass element in front of lens, with a reasonable amount of 'bash' protection from the metal sealing ring at the front of the unit
- the video mode! Have some excellent (IMHO!) footage of reef shark, and aggressive trigger fish... will post this in due course!
Con's:
- can't retract flash once fired
- no 'filter' for the flash... other cases have an semi-opaque sheet in front of the flash, which I _presume_ is to cut down on glare.
Thoughts:
- you need to be a confident and capable diver to use this (or any u/w camera).... I frequently found myself forgetting my buddy, my buoyancy etc, and not watching where I was going.
- beware of spending all your time looking thro the viewfinder, and not at your surroundings.... on land this is not so important, but there are agrressive/territorial fish!
- I get thro' a set of batteries (2.3Ah Sanyo's) in 2 dives
- don't forget to flip out the LCD screen before closing the case....
If you've any specific questions, drop me a line. Am off to Manado in Indonesia in a few days, more diving!
