Amazon Smart Control System Echo Dot Relaunched At $50. SWMBO has a full sized Echo in the living room, and she controls her music, and asks Alexa questions while she is doing whatever it is she does in the Living Room and Kitchen. I only come out of the den to annoy her. At least that is what she tells me. So, now that the Dot is here, and is only $50, I am going to join in the fun. Alexa, send me a Dot please.
