It blows it away but is a small step up, kinda at odds with that statement no? $1200-$1500 for a "small step" isn't practical. If you're into the latest and greatest thing and you've got the money, go for it, you only live once. From a business standpoint those MPP owners who use their drones more as tools than toys, I really don't see the need to upgrade; especially the liability involved in buying the latest and greatest.
It depends on how you use it I suppose. $1500 for that camera upgrade wouldn't be practical for me... but I have an Air and have been listing after a Pro for a while, so this was the perfect time.
From a business standpoint, I don't use them as tools, just toys.
