Yesterday's leak might have spoiled the surprise, but DJI was still enthusiastic about unveiling its new Mavic Air drone in rainy New York this morning. While last year's Spark was all about making drones accessible to a new generation of pilots, the $799 Mavic Air is a high-performance creative machine that just happens to be incredibly small. When folded up, the Mavic Air is about as tall and wide as a smartphone -- it's so tiny, in fact, that a spokesperson had a few crammed into his vest without looking the least bit frumpy. Despite its diminutive size, the Mavic Air can float around for up to 21 minutes on a single charge. DJI claims that's the longest flight time you'll find in a drone this small.
