Fully squaring up to Google in the smart home world, Amazon has gobbled smart home upstart Ring, apparently paying more than a billion dollars for it.

The acquisition is a smart one (geddit?) for the Seattle e-commerce monster, as it tries to build on top of its Alexa digital assistant but risks being outflanked by Google and Apple as they attempt to use smart home hardware to push their own digital assistants and app ecosystems.
