Changing your volume for your TV is rather stupid (using up/down at least, "set TV to X%" might work well but I love my remote so I always use it). For controlling lights I LOVE alexa. That plus things like daily briefing, weather, alarms, timers, and more make me VERY happy with my amazon units. And this is coming from a huge mac fanboy. Smarthome is where Alexa really shines IMHO.
