Your favorite ill-defined smartphone accessory is back, this time teasing us with talk of external speaker support (via mini audio jack) and wireless audio transmission. We did wonder why the Nexus One dock would have a Bluetooth connection when the phone already has one of its own, and the trick seems to be that the dock will act as the conduit through which the Nexus will transmit music wirelessly to your nearest set of banging sound thumpers. Simple, yes, but also rather liberating for your Eclair-sporting device. Makes that $45 price seem all the more reasonable, no?
