I'd just like to point out that AFAIK the micro-usb charging plug has been decided to be the unified standard plug for charging cellular phones (or more mobile devices in addition - but I'm not sure of that) for all the companies who makes those.
It means, that from now on all the companies (which signed the agreement) will enable charging via micro-usb port, thus reducing the amount of chargers distributed to the cellphones owners - so if you already have a phone which can be charged with a micro-usb plug and you got a charger with it, next time you buy a cell phone - no matter who produces it (Nokia, SE, Motorola, etc.) - you won't have to get a new charger for it because the previous one will fit just right.
In addition, it'd be less and less common to bundle the box you get with the new phone, with a charger - and if you still need one you could buy it separately. This will reduce cost for the cell-phone manufacturers and also be better for the environment, as you won't have to throw away your previous phone's charger each time you buy a new one...

This is, of course, just in case I'm remembering right and this agreement was signed, and don't imagine things
