There was a time, when people bought Nokia phones because other people had Nokia phones. That way there was nothing to worry about if you forgot your charger … there were always other chargers around. But now I have a Motorola, and I am as free as can be. It charges via USB.
What a relief it is, to know that the cable I carry around in my bag with my camera, will also let me charge my cellphone! Way to go, Moto! May the standards be with you.
