The dream of a vintage Polaroid instant film camera that also gives photographers the ability to share photos to social networks has finally developed into reality. Today at CES, Polaroid announced that its long-awaited Socialmatic camera will ship in the fall for $299. But the real fun comes into play with the built-in Zero Ink (ZINK) printer, which produces 2×3 full-color sticker photos in less than a minute, harkening back to the days when instant film was high-tech.
