Polaroid's Cube camera got a soft debut early this year at CES, but the prototypes we saw then have been refined into real devices — and it's just as tiny now as it was then. At just 35mm (a little less than an inch and a half) on each side, the Cube is one of the smallest "action cams" out there — the term meaning a small, rugged camera usually with a wide-angle lens and various ways of attaching to vehicles, helmets and clothing.
The idea with the Cube appears to have been to make an action cam as small and simple as possible. It has just one button on top — record — and under a water-repelling plug there's a switch that swaps between video settings, as well as a Micro SD slot for storage and a USB port for charging. It won't have the options or fidelity of a bigger, more full-featured action cam like a GoPro, but it's also significantly cheaper. You can pre-order one for $100; they'll be shipping later this month.
