It looks like any other mirror, and at 1.9mm thin, you'd be hard-pressed to guess otherwise. But the Duo AI Mirror is in fact a full-fledged computer hidden in plain sight. Its 27-inch HD multi-touch display hides until awoken, and can be configured to handle a variety of tasks, from showing the weather and news to letting you control your thermostat and lights. The "AI" comes into play in the form of Albert, the Duo's voice-powered assistant, who lets you handle a variety of tasks without needing to dirty the screen. A separate box holds most of the electronics — enabling that razor-thin profile — and runs a touch- and voice-specific operating system called HomeOS.
