For me size and weight are not just important, they are critical. The Mavic is a total game changer for me! . It's my first DJI drone and I ordered right after the announcement. (Normally, I'd wait for all the bugs to be sorted out but I knew that I had to order right away) When hiking for 12+ hours to remote locations and carrying a lot of required gear (e.g., climbing gear, food, water, clothing), it's just an option to lug along a
P4 size drone. Combine that with the fact that half the time or more, conditions prevent me from flying the drone.
