The drone can be piloted by either iPhone or Android smartphones, and it can also fly pre-programmed paths. Want to capture a group selfie but don't have any friends with a 40-foot-long arm? Snap can fly up, take the picture, and return to its pilot. Snap's propellers are enclosed in cages, so grabbing it in flight shouldn't result in scratched-up hands. It weighs about a pound, and can fly for 20 minutes with a top speed of 30 mph. It will pre-order for $895, a little pricier than entry-level camera quadcopters but significantly cheaper than specialized models, like the DJI Inspire. If it has a niche, it'll be hikers who want breathtaking photos without adding a ton of weight to their packs.
