The Amazon Echo and Amazon Echo Dot tend to yo-yo in price like the wind, seemingly depending on what kind of mood Amazon is in.
In our T3.com review, we called Amazon Echo Dot a 'no brainer' to buy. It's a hands-free, voice-controlled device that uses Amazon's voice assistant Alexa to play music, control smart home devices, provide information, read the news, set alarms and more.
Amazon Echo takes the concept a step further - it's a hands-free speaker, great for music, radio, news bulletins and more.
The Echo supports third-party 'skills' as well, so developers outside Amazon can write apps to let the device stream music from Spotify, read tweets or order a ride from Uber. There's no screen here, obviously, so every output has to be spoken back to you.
