Nexus One Dock might support external speakers, transmit sound via Bluetooth

While it might just look like a chalk drawing of a victim right now, this sketch is leading a lot of tech bloggers to draw the conclusion that the infamous Google Nexus One smartphone will have a dock accessory that supports external speakers.

According to Android Guys, the dock accessory has a mini-audio jack, allowing for connection to external speakers and thus transmitting songs saved on to the Nexus One. Furthermore, owners will be able to send songs over Bluetooth airwaves to an external source within 20 feet.

Sounds more flexible than other smartphones and their docks and accessories. But how much would one of you pay for such a gadget?
