Very interesting...I just popped onto DX to look for something and in their new products page they have new USB rechargeable AA cells. No charger needed! Just plug the battery into a USB port and power up. What an ingenious idea if it is executed properly. 
Johnny, it has a very believable 1450 mah capacity, doesn't it? Great idea though...
pretty cool.
I seen that some years ago, imho is not worth considering higher price and half capacity, better buy an usb charger, prices start from 1,5 $
And for me don't exist anymore NOT LSD NiMH batteries :P
