So the P4 seems to cover a lot of ground that the Inspire does. Short of some camera upgrades (which admittedly may make a huge difference, for sure), independent camera, I am not seeing a lot that adds value. Of course, the lower flight time and larger size are what sticks out to me more as I plan on flying in much tighter quarters. So what am I missing? It's more impressive, bigger and cooler. Some may see enough value in that to merit the premium. What are your thoughts?
