I have the D10. It's length and width is similar to all other P&S's out there, but it is thicker. A weird egg shape. I don't find it overly big, though. I'd think it should be included in the category here. Though if you go to Best Buy or similar box stores, they have no clue it even exists.
It takes very nice above water pictures, I'd rate it equivalent to Canon's other P&S's. For your standard, everyday picture in good light conditions, I think the sharpness is superior to my Canon SX20is. Though the SX20 obviously has a lot more versatility for more difficult conditions and specialty type shots, and light years better zoom.
Below water, I've gotten a couple decent ones, but nothing like some others have posted with Olympus and others. Not sure if it's the camera, the operator, or the place, or maybe a combination of the above.
The thing is bombproof.
