It seems premature to state "lead-free solder is a grand success" with only five years (July 2006 to July 2011) experience.

"Dr. Ronald Lasky, Dartmouth professor of engineering and a frequent 
blogger on solder, claims the transition to lead-free was a grand 
success. “A lot of people claim that lead-free solder is not as reliable 
as lead-based solder,” Lasky told me. “We’re now five years into the 
implementation of RoHS, and we’ve made $3 trillion work of electronic. 
We haven’t really noticed any big change in reliability.”"

I thought some of you may be interested in the above article.
