I couldn't see using an echo when I had my phone/pc that does everything.
Now an entry into the home could have been a digital assistant on the PC, Hologram, tv or app. So many ideas for profit streams, open API for 3rd party digital assistants with fees attached, alexa tv's running an app with a visual digital assistant, run the app on a tablet and see a digital assistant.
Even if it was a novelty, a little animated person standing on the countertop is way more interesting than speaking to an echo.
