The larger display and sleeker design on the second-generation Amazon Echo Show make a world of a difference over the previous version. That's good news since, as Echo devices go, the Show isn't cheap. Not only that, but it essentially serves as Amazon's reference design of how screens should work with on Alexa-enabled products. Amazon is continually working on the brains of its digital assistant, Alexa. My first introduction to the smart assistant was with the original Echo.
