It certainly was an interesting development when they announced it.

The challenge will be to get people to pay for something that doesn't stream mainstream artists nor do any of the things that the Alexa et al do.

However I have heard one of their Ambassadors talk about the possibility of paying fans in MC for listening to music as well as paying the artists. If they can make that happen then maybe fans can buy the speaker with the MC.
Then we have something exciting!
