Overoptimistic.<p>There is no insurmontable platform advantage. Microsoft&#x27;s Windows and Google&#x27;s Android are in their best shape yet and one can switch platforms without major inconveniences. Maybe there&#x27;s the exception of very specialized software applications not available on all platforms, but for most apps, they cost 0.99 because that&#x27;s what they&#x27;re worth. 
Hardwarewise Apple is best in class, but Lumias are fine and I&#x27;m guessing there&#x27;s Android manufacturers that don&#x27;t suck.<p>My point is that yes, you probably won&#x27;t get such a good overall package from anyone else except Apple, but that package does cost a ton of money, and you can get something more than decent for a third of that price. 
Can&#x27;t really imagine what an Apple car would do that other cars couldn&#x27;t, except maybe driving itself, but then I don&#x27;t see why Apple would beat Google &amp; the others to the punch.
