The Amazon Echo, a smart helper running Alexa (I know I’m going to make some of my friends at Amazon angry by writing it, but Alexa is Amazon’s Siri), is a very cool device that can do anything from playing music to ordering things from Amazon. To activate it, you just have to say “Alexa” and then ask for whatever it is that you want: “Alexa, please wake me up tomorrow at 5 am.“
