NEW: Amazon begins drone delivery in the Dallas, Texas area, some residents say the buzzing is driving them nuts. One man, who spoke with the Dallas Observer, says the drones are flying over his house throughout the day, calling the high-pitched noise "annoying." He did admit, however, that he has used the delivery service, calling it "pretty cool." The drones can carry packages up to 5 pounds and can deliver them to locations within about an 8-mile radius of the Richardson Amazon facility. Prime members pay just $4.99 for the deliveries, which can arrive in about 30 minutes.
