I really like this. Executed properly, it will solve WiFi issues for medium to large in-home deployments. I think the killer angle is the ease of setup and configurability. The most important tech here to me is the fact it promises to self-update and try its hardest to never stop working. If their marketing is accurate, I'd recommend this in any simple deployment requiring more than one router. (Say, throw it in your parent's large house and trust it will just keep working over time)

That said, a current-gen AirPort Express or Extreme covers many of the points here.

- You can set it up in seconds from your phone, if you have an iPhone. (Otherwise, you're stuck with OS X, Windows, or the Windows utility on WINE, though there are some okay open-source config utils).

- It's going to be pretty much rock solid. They're very good about reacquiring network access, and the firmware is about the cleanest I've ever seen on a router from a technical perspective (the iCloud services are a bit weird, but those are optional).

- You really only need one of them to serve single-level homes /apartments where they'll be punching through less than 5-6 walls.

- It won't auto-update, but some might consider this a feature.

- If you plug a second AirPort in, it asks if you want to extend the first network.

That aside, the bandwidth reduction from a multihop mesh would likely make the Eero unsuitable for my needs (I tend to saturate AC, so I just throw more wired access points at the coverage problem to keep my bandwidth up).
