Today (Sept. 27) in Seattle, the company unveiled a new version of the Echo, a small mottled-gray cylinder designed to blend into its surroundings, as well as a larger, shinier Echo Plus, and plenty of other stuff. >Perhaps the clearest sign that Amazon is investing big in the Echo and the virtual personal assistant that goes with it, Alexa, came from a comment made by David Limp, Amazon’s senior vice president of devices and services: More than 5,000 people now work just on Alexa.
