As a "read me the news, play NPR or BBC or Podcasts, tell me the weather, make a shopping list" kind of device, to play music in various places, to manage a lot of the automation in the house, to listen to audible books, to buy music.

I have Echoes in the bedroom and kitchen/living room and a Tap that floats.

NB: I work for AWS but am just an general Alexa fanboy (and I am definitely a lot older than 27).
