Will Amazon's Echo take off in the UK?

Amazon is expected to confirm shortly that it is making its artificial intelligence-enhanced speakers available to the UK and select other countries in Europe. The Echo devices are controlled by their owner's voice and can be used to answer questions, control other smart home kit and buy goods from the US retailer. The tech is still fairly "clunky", according to the BBC's technology correspondent Rory Cellan-Jones, but it points the way to how virtual assistants could play a role in our lives beyond the smartphone.
