For people who are wiring an Echo Dot into their Sonos Play5 or Connect Amp you might want to check out the new Echo Spot. I just replaced my Dot in the Dining Room, which feeds a pair of Play5 Gen1s, with an Echo Spot and immediately noticed a few cool things about this setup.
First, like the Dot, you are dealing with full Alexa so you get all Alexa features including Drop-In, only now they are video calls.
You also get a nice display for artwork and lyrics in a form factor that doesn't take up any more space than the Dot did and is nicer looking than the Echo Show. The display can also do useful things when you are not listening to music like alert you to upcoming events on your Google Calendar or display video of your front door camera.
The screen also lets you set up and manage the Spot without needing to fish out a phone and fire up the Alexa app.
And with this wired configuration you can still use the Sonos app with your Play5s or Connect Amp if you want to use your local library and gapless playback.
Of course the big barrier now is the cost which is just $20 less than an Echo Show but if you look at the price history of the Show it is reasonable to expect dramatic price cuts for the Spot over the next year... maybe to the point where Amazon doesn't feel they even need the Dot anymore.
