I got my new DJI Inspire 1 quadcopter last week and have been having fun with it:
You can see the sunshade for my iPad with live video. My SMB is in the new barn at the back left in the shot from about 400 feet up. I posted a video here:

Some background. I got the idea for aerial photography last December and started out with a Hubsan X4 H107C 4CH RC Quadcopter With HD 2 MP (about $70 on Amazon) and practiced with that while we spent our winter in TX and AZ. The photos are low quality but it was great for learning how to fly. I took it up a couple hundred feet and lost sight of it a couple of times. I figure you need to be good with the controls and know what to watch out for before you get the expensive one.
I am happy with the wide angle lens (20mm equivalent). Although a longer one would be nice, there are several problems some of which were mentioned above. Longer focal length means smaller depth of field, a problem with a fixed-focus lens; the decreased field of view means it is harder to aim right; and longer means it has to be more stable for sharp images (or shorter exposure time). Having said this, DJI will probably come out with new cameras for this quad and in the mean time I will get lots of experience and fun shooting with this one.
Let me know if you have questions.
