two things i would like to know about the canon g11...
- Life Expectancy
- Battery 
         Battery Life?? 
         How long the battery lives for??
                    How many times can it be re-charged before dying out??
overall i prefer the g11 but i've also been looking into the ricoh gx200 which seams to be a pretty good camera as well - a particular feature that i like about it that the canon g11 doesn't have is that the ricoh gx200 can be powered on AAA batteries as a back up feature. any help?? 
:) thanks
