I disagree.Should have had a proper display from the start imo.
I don't see what they add really. The Amazon Echos have been a bit of a let down in that Amazon have latterly forced non-switchoffable ads which ruins the whole experience.
Whereas Apple will certainly NOT be using the screen to advertise... the strength of a smart speaker is to be an inconspicuous object in the room listening out for, and responding to, commands.
Having to walk up to it to interact immediately takes something away from its convenience.
Sure, Siri needs to be better at listening and understanding but thats where they should focus and not on a dust-gathering screen which has very limited use.
