Small but mighty, this palm-sized computer is a popular pick on Amazon wish lists this year. The Echo Dot answers questions, sets alarms, reads your calendar, orders dinner, calls cars, and more, at the request of your voice commands. Plus, this tabletop device can automate compatible devices around the home, from lights to locks and from sprinklers to sound systems. And, luckily, there's no need to wonder whether your recipient already has an Amazon Echo: The Echo Dot is compatible with but doesn't require an Echo to get started streamlining the day-to-day. Available on Amazon; $49.99.
