I've been quietly following this. Having noted the extra USB in the m240i that I tested at the time of my order my CA agreed that this was a new feature. I took delivery of my blue baby yesterday and can assure you all that the extra plug is only included with the wireless charging option for USA builds. I had already set myself up with a 90 degree USB adapter to provide a nice interface for the 3D printed iPhone cupholder everyone else has used. Add in a flush 12V USB adapter and everything is peachy. I have an Escort Passport radar detector that requires a cigarette lighter plug, so I have just now purchased ANOTHER adapter that provides 2 extra USB's. Everyone's happy...
This car is fabulous, BTW, and aside from the fact that I had to wait in Seattle while the car sat at my dealer in CA, and I've had rain nonstop since I've picked her up has done NOTHING to put me off my decision! Holy crap, this thing moves NOTHING like my 335i. My wife and 7-yr old daughter have been unable to control their shrieks in our brief driving episodes!
