The Nexus One was and is a great smartphone. It may not have sold for crap, but it has managed to draw a great deal of love from the nerdiest elements of the tech community. For example; NASA's Ames Research Team. They've posted up a video (via Phandroid) of a rover being controlled via the Nexus One.

The "remote" works via Bluetooth and an Arduino board on the rover. Scientists won't be using their Nexus Ones to control this thing once it lands outside of Earth, but the fact that they are fiddling around with tech in this way points towards some very interesting future avenues of development.
