Miniature UAVs already exist, and DARPA is working hard to make
them the size of flies. Autonomy is a different ball game though.
When it comes to general monitoring devices, privacy is long gone.

are constantly snapping pics every which way, and Google is trying
to scan in the whole planet?...
The Robivie-PC is just a toy, for the moment, albeit an expensive one.
