Guess I've kinda waged my own personal campaign by "voting with my pocketbook" for awhile, restricting, whenever possible, my portable electronics-buying to AA-powered devices: GPS, radios, (LED) flashlights etc.

AA's are reasonably-priced, small in size/weight, universally available, rechargeable, come in several flavors (lithium, alkaline, NiMH), and allow redundancy among devices.

The rare exceptions for me are things unique in form and function, such that their design precludes AA usage. Perfect example – the Photon lights.
