Free the drones

摘要

One of this year's top-selling Christmas presents is a drone. For $50 you can buy a tiny quadcopter with a video camera, perfect for snapping a bird's-eye view of your garden; for $700, one equipped with a gyroscopically stabilised camera which, when paired with a wireless tracking device on your wrist, will film you while you ski, cycle or kite-surf. More significantly still, as our Technology Quarterly outlines this week, drones could revolutionise all sorts of businesses.
