Interface not great

Use regular inertia dials for the interface. The simulated camera controls are difficult to read. Also no one thinks in decimal feet, change the calculation to show feet/inches. People will REALLY appreciate that.

Educational tool.

Great for the beginner or someone who just made the move to a DSLR or one of those great 4/3 jobbers.
