...“most electronics has a useful life of 3 years”...

Look, we essentially need to resign ourselves to the reality that the 
microcent mindset of the component industry has found a significant boon 
in the socialistic agendas of RoHS; and that equipment producers are 
enthusiastic accomplices to the entire effort and its value as a means 
of forced obsolescence.  As usual, just follow the money...

Until the sheep actually care enough to KNOW the causes which they give 
lip service to, this type of malfeasance will continue unabated.  Wake 
up people: Virtue and responsibility is more than just soundbites and 
warm feelings.  So much "Hope," so little "Change;" and Nobel Prizes for 
dead things like Al Gore.  Irrespective of presumed education, does 
anyone out there think anymore?

At its root, I believe this all is the harvest that we have reaped from 
a series of generations which lost most of their sense of wonder and awe 
somewhere along the way; and all sense of pride in knowing and loving 
the world around them.

Thank you again, gentlemen, for your viewpoints and your efforts.

Good evening.


Marcus Thompson
