Amazon using drones- surely not?

The big news yesterday was that Big Chief Amazon admitted that they were actively researching the possibility of using drones to deliver packages.
Is this really new? No disrespect to hardworking postal workers everywhere (especially in the weeks before Christmas)but...judging from the vacant-looking moron who keeps leaving my stuff out in the rain or takes it to the wrong house or swears I wasn't at home even when I clearly was, they've been using them for quite a while already.
