It's ridiculous, I have to carry a couple Costco AA batteries in my pocket. Maybe 50 shots with flash and the batteries are spent. Otherwise, I have quite the boner for this little camera. Seems to work great!There is a few kicking around, but they usually aren't great for one reason or another. G10 is a great camera with all manual controls, but is bulky and heavy. I am not 100% sure if the A series still has full manual, but they still do chew through AA batteries in a hurry.
One day back at my old newspaper, the staff camera (Rebel XTi) died suddenly, so I shot everything with the lil' A510, and no one noticed. Looked great in print!
I don't doubt the G10 is good, but I'm not going to upgrade from the powershot until I crash and ruin it. (Which will probably be the next ride, now that I've typed that)
