Your home is about to get a whole lot smarter. On Monday, Amazon announced its artificially intelligent bluetooth speaker—the Amazon Echo—is being made publicly available for purchase. The Echo was first unveiled in November 2014, but it was sold on an invitation-only basis until this week. The device is one of the first always-on, voice controlled intelligent home appliances that connects to the Internet and controls third-party services. It can answer trivia questions, tell you the weather, add items to a shopping list, and much more.
