While the device’s logo was taped over, there’s no mistaking it — Google CEO Eric Schmidt just gave a live demo at the Web 2.0 summit with Google’s upcoming Nexus S smartphone. He called it an “unannounced phone” from an “announced manufacturer,” but the device used in Schmidt’s demos was outed last week and it is indeed none other than Google’s Nexus One successor. As for new info, there really isn’t anything to speak of at this point. Schmidt just mentioned that NFC technology, which is supported by Android 2.3 and included on the device he showed off at the summit, would eventually replace credit cards. He then joked that while he admits to having said Google will not be releasing a “Nexus Two,” he never said anything about the letter “S”.
