Add Alexa to any room. Only $49.99
The All-New Echo Dot uses the same far–field voice recognition as Echo and is a convenient addition to any room of the house. Directly connect Echo Dot to speakers with an audio cable or via Bluetooth, and add voice–control to your home stereo system. With its built–in speaker, you can place Dot in the bedroom and use it as a smart alarm clock that can also turn off your lights, or use Dot in the kitchen to easily set timers and add items to your shopping list using just your voice.

This seems to point to more multi point, communications and control examples that could be put in play. House or household wide. Most of the examples being shown are music control examples, rather than 'serious'. Would like to see more of the latter developed for voice control. Have some ideas in the area of health and elder care.
