Cindy wants to know about the Amazon Echo. Leo says that the cool thing about the Echo is that Amazon opened it up to create more functions for it, called "Skills." To date, the Amazon Echo has over 3,000 skills it can handle. If she's an Amazon Prime member, she can tell it to buy stuff and ship it to her. She can tell it to stream music, too. If she has a stereo system, she can save money and get the Amazon Dot and plug it in.
