IMO, the choice between radar and nexrad info comes down to whether or not
you have the choice to make the flight or postpone until you have better
weather.

A friend brought up an interesting question.  If a plane is big enough
 to support onboard weather radar, and also has the XM satellite weather
 link from ground Doppler radar, is it possible to integrate the two
 sources into a single display?
 Related question: If you could choose only onboard radar or XM weather
 link, which would you prefer?
