Google’s $35 video-streaming dongle has drawn predictable comparisons with the Apple TV—Cupertino’s perennial “hobby” that, at last count, sells some 1.5 million units every quarter. And why not? The two devices are, on the surface, very similar: They both stream video, and both are part of attempts by their respective manufacturers to dethrone the traditional living room TV experience.
