When we first saw them we thought they were cool, but now that we've seen a review (at TrustedReviews.com) we're definitely getting some USBCell Batteries for ourselves. They are amazingly convenient, requiring no charger, just a USB port. They hold their charge well, charge quickly, and have enough stamina to take over 500 digital pictures with a Fuji Finepix.

I should remind everyone that you get better efficiency out of a wall charger, because the current doesn't have to go through the inefficiency of your computer's power supply, but it also doesn't suck power from your wall when there's no batteries plugged in. At $24 for a pair of AAs, it's a bit expensive, but well worth the price if you ask me.
