See Chris Carlson's "Get Coordinates: New in 6.0.2", Wolfram Blog, 
(March 11, 2008),

http://blog.wolfram.com/2008/03/11/get-coordinates-new-in-602/

This blog entry contains numerous interesting examples of various usages 
of this new function (zooming on a specific part of a plot, computing 
the area of a polygon, etc.)
