We became a little dispointed with Nikon after this 5600. The pictures are not really any better than our old 2MP HP and its not holding up very well.
I had always stayed away from propritary betteries but am finding that the smallest cameras are too small for AA's. I don't know why they can't make them run from AAA's the mAh of those super expensive Lithium Ion's isn't any better than the 850mAh or so of an AAA. Thats why I'm wondering about the phone/camera combo, if there are any decent camera phones since phones all have the propritary battery anyway.
Then canon annoyingly uses a different prioritary battery for their camcorders which we have. Even though the specs are the same (V and mAh) its physically shaped differently so those won't interchange.
