This has been an utter lifesaver. You can have as many devices as you have, and more plugs and wires trailing across your desk, and taking up valuable multi-socket space. The logical next step is to ditch all of your chargers and to replace them with one, unified device.
It plugs in by USB -- which you should now have at least one spare -- and you can charge all of your devices. It supports BlackBerrys, iPhones, even Nokias, Samsungs and that magic European standard, micro-USB. Granted, you can't charge all of your devices at the same time, but it's a handy piece of kit to have on hand.
