Apple is a fantastic company, but they are in the Consumer Products business. If history has taught us anything, it's that likes and dislikes of customers are subject to change - and often very quickly.
As for the Apple car - that sort of a thing is a joke to me. Yeah - maybe they can throw a zillion dollars at it. But what the hell do they know about building a car, working with automotive suppliers, etc? Further, there are already status symbol cars out there - something that really wasn't there in cell phones. As a stock holder, I'd be somewhat pissed if they went into this business. Now building the interfaces to the controls, that's a different story.
