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.
