Legitimate wall mount option
We all know that Nick and the other eero guys like their "put you eero out as a room decoration on your coffee table" mantra.
But there really are times when you need the device up and out of the way. If an eero was *made* to mount on the wall (with antennae directing signal in a semi-sphere towards the room) and ethernet and power ports on the "wall side" (think Nest wired smoke/fire detectors) it would be less obtrusive with fewer exposed cables.
You could market them the same way as you do Beacons: one or two paired with normal devices that are used as gateways.
