Sam, if the Platinum was out when you picked up yours, would you have bought it? I get the extra few minutes' flight time and quieter operation, but right now the standard Mavic Pro is $200 less. Not sure if that extra flight time and fewer decibels are worth 200 bucks.
There's one out there of a flight over Conowingo, Sam. A little too shaky for my taste, but it's impressive that you can see an eagle flying at the same height as the drone.
