Four early employees of Nest Lab, acquired by Google last year, have opened the first brick-and-mortar store dedicated to the Internet of Things. Located in Palo Alto, the software-powered store, b8ta, currently has 60 items, some available at Best Buy and many heretofore only available online. The category range includes: connected home, electric transportation, smart toys and sensory augmentation devices. In a twist, b8ta's business model relies on manufacturers paying a monthly subscription fee to be in the store. The Los Angeles Times likened the relationship to slotting allowances charged by grocers.
