I'm finally going to jump into UW photography - keeping it basic for now with camera and Canon WP case. But I'm debating whether to get the G9 or the A650IS. I'm thinking I'll mostly do basic "ohh, look at the pretty fishes" pictures to show the family 
The two reasons I'm not sure about the G9 is
1) the lack of a pivot screen. I realize it makes no difference for UW photography, but I really like it for topside shooting.
2) proprietary battery. Requires at least one extra battery and may leave you without power in a pinch, where the AAs for the A650IS are easily available.
The A650IS has the pivot screen and uses AA batteries, and with the CDHK hack it looks like the A650 gains some, if not all, of the software features of the G9 - most notably RAW. The A650IS lacks a hot-shoe. From the specs it looks like both lens and sensor of the two are very similar, if not identical. For continuous shooting and general speed the G9 has the upper hand.
Any thoughts on one over the other, other than what I've mentioned so far for my very basic shooting needs?
Thanks
