Amazon Echo Dot review: here comes the Alexa army

Amazon's Echo is often referred to as a Trojan Horse. Slid into your home under the guise of a wireless speaker, the Echo has grown to become one of the best ways to control smart home devices, such as lights, thermostats, locks, and more with just your voice. It turns out that it's much easier to turn your lights on or off with a voice command than to pull out your smartphone, unlock it, load an app, and push a button. The Echo also lets you set alarms, timers, catch up on the news, and yes, buy things from Amazon with simple voice commands. And its wireless speaker capabilities have expanded with support for Pandora and Spotify.
