I love a camera that works without batteries. I have had several occasions where I have hiked out into the middle of nowhere for several hours, or it is Christmas dinner and the batteries die or are dead. If it takes AA's, that's not a big deal but if it takes a specialized battery that needs a specialized store to buy, that is more than annoying. I can usually guess at the metering but still need the camera to fire. This of course limits you to manual cameras of the older variety but I like those kind anyways.
