Google is completely revamping its smart home ecosystem around Gemini, and a tiny orb will be the face of the overhaul. It’s the Google Home Speaker, a spherical and stylish speaker that’s made to fit in anywhere in your home. You can use it as a Gemini-powered assistant, a home listening station, or as a stereo pair for your Google TV Streamer. In isolation, the Google Home Speaker looks incredible.But the more I learn about the Home Speaker, the more questions I have about how it’ll fit into Google’s smart speaker lineup at $100. We already suspected the Home Speaker would leave buyers looking for a Nest Mini alternative high and dry, but that’s not all. Google’s official reveal confirms that the Home Speaker isn’t a direct replacement for the Nest Audio.
