I've said this before and I'll say it again and again and again and again...
If you buy a camera with a proprietary battery, you're braindead in my book...at least on that front. I know that's strong language, but it's something I feel absolutely strong about - at least the way (and locations sometimes) that I shoot.
I will never own a camera that I cannot load up at a 7-11...or a roadside mud hut in Ethiopia or a plywood shack in Costa Rica (yes, both have happened). I would have missed way too many shots irrespective of my preparation (Mr. Murphy and I are on a first-name basis).
Even my new camera, the Pentax K-3 (high-end DSLR) has the option of using 6x AAs in the battery grip. My older cameras (two 12mp Pentax K-x) take 4x AAs (I use a rotating stock of Eneloop rechargeables for those...and keep some energizer lithiums in the bag).
There are also still a variety of point-and-shoot that take AAs (many of which do recharging on the camera using USB).
My first criterion in selecting a new camera - batteries that are available worldwide - for those times that Mr. Murphy is lurking.
Your mileage may vary, of course, but I feel very strongly about this one. I have SO many fantastic photos I would have missed otherwise. And I've seen other photographers lament drained batteries in the middle of shoots - with absolutely no recourse. Imagine how nice it would feel to have an 8-pack of duracells in your bag as backup/insurance...and KNOW that you didn't need to worry about your camera going dark.
