Does anyone think Apple will allow it to play from any music streaming service?
Or do you think they will lock it down/limit it to only Apple Music?
So users of say Spotify, who may currently have a Amazon Echo, or Google Home, or Sonos, and may fancy an Apple Speaker won't be able to make use of it?
Apple Music only for now, unless they open it up in the future. If you currently have one of those products, not sure why you would prefer this.
