Samsung clearly wants to interoperate with iPhone/Pod/Pad enabled docking devices by using the same usb/docking port. Accusing them for using it is like accusing laptop manufacturers for using mini-displayport.
The plug is actually not the same as the Apple plug. That plug is Apple proprietary so Samsung would have to pay Apple some serious cash if they used it. They just developed their own lookalike cable.
Then there is no point in it. What the hell Samsung?
