Agreed. It looks a little like a squatter Echo. Cylindrical, ring of light at the top. But I suppose Amazon will avoid any legal action since it's pretty tough to win a court case with the argument "they copied my cylinder." Hopefully the different functionality of each device will keep any ugly legal battles from ensuing.
But with the a computer embedded in this router along with a speaker and bluetooth and zigbee radios this could be customized to offer a lot of the features that the Echo offers (minus the voice control). I hope that doesn't cause any problems.
