The Amazon Echo is a black cylinder that you can actually talk to. It can tell you the news, weather, can help with math, find information, and more. It's abilities can be expanded on even further with the use of Alexa Skills.
You can search skills that others have created at the Alexa Skills Store. You can add games like Jeopardy and math games for kids, a workout routine, and connect your internet-of-things devices like Nest and Honeywell.
