I agree. In fact, this article reminded me of hospitals that are using carrier pigeons to transport blood samples to a lab for analysis. So why not using drones instead for this kind of tasks? The Amazon announcement may be in part a publicity stunt, but I do not think it is a hoax. This is a viable business. The only question is how much time the FAA will need to create the necessary regulation to allow it. 5 years is a relatively short time for that, but for very small drones carrying little packages (i.e. less than 100g), that may be sooner than we expect.

The sense of smell of a dog with the human brain to interpret it. For now, using dogs for smell detection is quite limited. Dogs can not be trained to detect different categories of objects. Everybody knows about dogs looking for explosives or drugs, but you cannot have a dog to search for both, tell you what kind of drug or explosive is there, and then follow the trail of the person that put the stuff there. Think about all the things dogs are used for smell: termites and other hidden pests, hunting, illnesses (a hot topic for research) and how limited we are by the fact that we barely understand the dog.

Most game consoles (and especially Xbox 360 and PS3) are sold under their factory cost, so cloning them is not really interesting, as you compete with hardware which is outrageously cheap to begin with. Obsolete consoles are cloned because it is the only way to get a new one. Manufacturers want to clone Macs and Mainframes because those are sold with comfortable margins, so making and selling a cheaper version of them is possible, while still making good money.
