The commercial of course always shows the unit being perfect/flawless... but just as we know with Google Now and Siri -- having to repeat yourself over and over until the unit understands exactly what you want is a problem, especially in a noisy environment. These people never have a TV on? No music playing anywhere else? If music is playing on the Echo, how well will it pick up your next request? I'd love to test one of these things out... just saying, lets hope the reality is even CLOSE to the "marketing" commercial.
