Pro Already has documentation of being used as a hacking platform
The team at Hak5 has been doing weekly updates on their show detailing their progress with turning the DJI Phantom 2 as a hacking platform. They have it carrying a portable battery, a WiFi Pinapple and a prepaid Android phone. Updates can be found on their show here.
Pro Top of the line Flight Controller
The DJI Phantom 2 uses DJI's most advanced flight controller, the Naza-M V2, which has features such as advanced flight stabilization and hover, and a GPS waypoint flight planner.
Pro Already has an area to add a payload
The DJI Phantom 2 is made to carry a camera but your own payload, such as a small computer and antennas can be carried instead. The Phantom 2 can carry up to 300 grams of additional equipment making it capable of carrying a small computer such as a Raspberry Pi along with small antennas and a battery. Even if you don't have a compatible mount, the arms underneath make it easier to create your own "mount" for placing whatever it is you need to carry.
Con Most expensive option
Without any accessories, the Phantom 2 costs about $680 USD which makes it the most expensive option here (excluding a tricked out DIY drone.) Like the 3D Robotics IRIS, a gimbal and camera can be added which brings the full cost to about $1200 USD, meaning this is more than a device for hobbyists.
Con No API available
This drone has no supported API to control it from your own application.
Con Flight limited by GPS
After a Phantom 2 landed on the White House lawn, DJI released a firmware update that limits takeoff and introduces a max ceiling in certain areas.
All airports have a 1.5 mile radius no-fly zone. Between 1.5 and 5 miles, the maximum ceiling gradually increases from 35' to 400'
There is a 15 mile radius no-fly zone around the White House. DJI UAV's will not be able to take-off when in the White House zone.
