As you may of heard, within a few years Amazon wants to start delivering packages by automated helicopters. The plan is packages weighing up to 5 pounds could be delivered within 10 miles of a fulfillment center in about 30 minutes. Seems like this would leave the package on the sidewalk instead of at the door. Possibly on the roof if you want it to. Personally, I'm of the "I've lived without it this long" philosophy and take the cheapest and therefore longest delivery option available. I also live nowhere near any fulfillment center so I can't see using this. It occurs to me that brick and mortar stores that have been taking it on the chin thanks to online ordering would make good drone launching centers since they are already distributed across the country. Sounds like a cool, futuristic idea. I remember they used to say one day we would have televisions thin enough to hang on the wall like a picture, but maybe this will happen instead.
