Surely it's just "ok google" or "siri" in a tabletop device. We already have this as an app in our phones. Doesn't seem to be a technological move forward just a re-packaging of currently available ideas.

The big idea here though is that Amazon can get entrenched as the first such domestic fixed device and then control the fulfilment for the shopping/wish/gift lists you make using their device.

It's business innovation.
