What is Amazon Echo and how good is it?

Apple has Siri, Google has Google Now, and Microsoft has Cortana, but what does Amazon have? Well, while its still pretty hard to get a hold of, Echo is Amazon’s own personal voice assistant but what separates it from the other offerings is that it isn’t locked inside of a smartphone. Rather, the device comes in the form of a cylindrical gadget that is supposed to rest somewhere in your room and will essentially serve as the center og your smart home.
