Sure, but I'm into politics, so I've learned to judge by results rather than claims and reputation.

And there isn't a drone on my doorstep yet.

If there ever will be one, someone needs to announce it first. And if the timing is commercially interesting for Amazon, that just reflect the fact that Amazon is a company with financial intereste, just like any other company.

what's even more exciting to me is that they could develop their own complete distribution system by pushing cheap drones out to the edge of their network.

Warehouses->Jets->Drones

with barely any people in the entire process to slow things down and make it expensive.
