Seeing an image or two is one thing, but there’s nothing like seeing an unannounced, highly anticipated smartphone star in a crystal clear video — especially when the CEO of the company behind the phone is the one showing it off. Eric Schmidt decided to bring a shiny new Samsung-built Nexus S on stage with him at the Web 2.0 summit yesterday, and O’Reilly Media managed to capture the whole affair on film. The unreleased Gingerbread phone is looking awfully sexy, though plasticky, as Schmidt fondles it while discussing NFC. Hit the jump for the video and get ready for a formal unveiling Google’s Nexus S, which will take place in the next few weeks.
