Amazon wants you to be surrounded with Alexa--wherever you are

The news: Amazon unveiled a dizzying number of new gadgets yesterday, including wireless earphones (Echo Buds), a smart ring (Echo Loop), and smart glasses (Echo Frames). They all provide hands-free access, so you can ask Alexa to play a song, give you directions, or whatever else you may need, on the go. The products cost between $129 and $180 each. What's behind all this: Taking these three products together, there's a clear push to move Alexa beyond the home and onto your body. While Google Assistant is embedded into Android smartphones, people currently use Alexa only at home, and there's no Amazon smartphone.
