As a mark of just how serious Apple is about its smart home initiatives, the company has built HomeKit into 46 of its brick and mortar stores. That means if you stop into the Union Square location in San Francisco or the World Trade Center and Williamsburg stores in New York you'll be able to give the IoT suite a test run, TechCrunch writes. Some 28 other stores throughout the country will have the demos up and running. If you don't have one of the fancy stores, you'll have to settle for non-interactive literature and the like. Ugh.
