What's next for an energy-efficient thermostat designed by ex-Apple engineers? A limited promotion with a utilities provider to make it even more legit, that's what. Now that Nest has broached online mega-retailer Amazon's virtual shelves, the next stop on its trendy household domination tour's taking it to Reliant, a Texas-based electricity company. Bundled into the utility's "Learn & Conserve" plan, qualifying residents that sign-up for a two-year rate will receive one of the stylish, WiFi-enabled units, making the business of managing their energy settings a stylish and remotely controllable (via Android or iOS app) affair. Of course, you don't need to be a resident of The Lone Star state to call one of these your own -- Best Buy, Apple and Lowe's will also eagerly claim your cash in exchange for this home-monitoring wündergadget.
