Last year, the European Commission wanted harmonization of chargers for mobile phones, and therefore connectors for a micro-USB port to allow recharging.
Several manufacturers of telephones and smartphones (Nokia, Samsung, etc.), including Apple, had agreed to make their devices compatible with the micro-USB standard.
Out of the 14 signatories, some will already offer in 2011 phones, smartphones and chargers compatible with the micro-USB standard destination of the European Union. Regarding Apple, it would not be obliged to replace the 30-pin dock for a micro-USB port ! It could simply offer a dock adapter to a micro-USB connector to allow recharging. Apple also won't have to wear a micro-USB port in addition to the dock connector.
We discuss it on the forum.
