Wife got me an Echo Dot for christmas... at first, I kind of was like wtf is this thing too, but her and I've been playing with it all night. It's actually pretty cool how well it works. You can literally tell it to play any song you can think up and oddly enough, it finds it and streams it for you. It also will set alarms, interface with other smart devices such as lights, etc... tell you the weather, the forcast, etc...
For kicks, call it a fucking bitch and listen to it's response... this set my wife on a 20 minute tirade calling it everything thing she could think of.
