It would also appear that Apple will stick to its 30-pin doc connector as a source of power and a way of syncing rather than switching to the industry standard USB solution chosen by other competitors.
The change in the dock connector could be due to a change in the internals of Apple`s next gen tablet. The rumored Retina display could be one reason. Still, all these are called rumors for a reason.
Awaiting more iPad 3 talk.
