That's what I mean. Get a Google-blessed phoneless version of one of these things - something like a Galaxy Discover or other crappy 3.5" phones but without the anemic processor or pointless rear-camera.

Call it the Nexus 3, sell it for $100 - same price point as the iPod Nano, but with actual wifi and a real OS instead of being a pure media player. Sell a nice little boxed set at Costco of a Nexus 3, ChromeCast and a charging dock for the Nexus 3 device at Costco for like $140.
