Why do we need so many things that require charging? The other day I asked myself this question again and again as I plugged in charger after charger to power up my laptop, phone and walkman respectively. It was as if they all had conspired to run out of power at the same time. And I needed to use all of them that evening. :-(

Why can't someone come up with gadgets intelligent enough to charge themselves as soon as they sense low battery power? Or better still, gadgets that don't need charging - ever :-)
