Amazon Echo Dot (2nd generation) review: This is the Echo most people should buy

When I reviewed the Amazon Echo 13 months ago, I predicted that people would want one in every room. The Echo can control your home's lighting, play music, estimate your commute time, operate a timer, answer trivia questions, read books and news bulletins to you, tell you which movies are at your local theater, and so much more. You can order a pizza from Dominoes, a ride from Uber, or virtually anything from Amazon. You'd want one in every room so you didn't need to walk to the room it was in to use it, or yell "Alexa!" from across the house to get its attention. I'm sure Amazon loved my idea, but it was never going to happen on a broad scale at $180 a pop.
