To be honest, I don't know why they connector being changed is even a contentious point.
The contentious point for me is how come Apple dont obey by EU law and have a micro USB charging port? Do they get fined for it?
Guess the fuss is because loads of people have docks etc and now they have been shafted, also a bit of a shaft to those third party companies making the stereos with docks etc especially as the accessories have helped drive the growth of the iPhone. Guess on the flipside these companies have also made a nice bit of wedge out of it.
