Brainstorm: Could the incessant "iPad mini" screens actually be for... wait for it... Car stereos???
I'd kill for an apple car stereo that will AirPlay from the iPhone in my pocket without me having to noodle the phone. In fact, take the calls, too, and voice text.
The only challenge I imagine is the many different kinds of stereo internals in cars... If that's actually true. If it's not an issue, it's a slam dunk.
