+## Future Plans ##
+
+In 2010, two v0.1 prototypes were assembled, and the hardware was tested.  
+Unfortunately, this design turned out to be too expensive to manufacture and
+sell.  We then worked on a cost-reduced v0.2 design, which worked ok, but
+just wasn't very satisfying to use compared to a TeleBT and Android 
+device.  It's possible we'll come back to TeleTerra at some point in the
+future.
