I think these little USB rechargeable batteries are going to be huge. They are NiMH cells, rechargeable at any USB port. You don’t need a cradle and cable. Just charge and go. Not only are they easy to use, but they are nicer for the environment, by preventing the disposal of lots of regular batteries. I don’t remember all the chemistry of batteries in landfills (those grad-school brain cells have been taken over by new bits of information, like the names of all four Wiggles), but batteries in landfills are bad!

In addition to AA cells, they will be available in AAA, 9 volt, and sizes for cell phones and PDAs. Visit usbcell.com for more information.
