Answer Wiki. The Amazon Echo and Amazon Echo Dot are stationary devices (they need to be plugged in). The difference between them is that the Amazon Echo has a much better speaker built in, while the Dot is intended for use with an external speaker via line out/Bluetooth. The Dot is much smaller and cheaper so if you want Alexa in multiple locations, it's the best option.
That's an option with the pint-sized Echo Dot, but not with the full-sized Echo. Amazon seems pretty committed to the idea of the Echo as an all-in-one device. All of that said, the Echo is more than a music streamer, just as an iPhone is more than a telephone. The key is Alexa.
