Point taken, but we'll see.  Miniaturization comes at a price.  No one 
ever replaced panel-mounted phone jacks as frequently as we do 
circuit-board mounted miniatures today.  Nor did we replace mic cords 
and plugs (same with telephones) as often as we have to today.

My overall thesis on dependability still stands, I think, as witness the 
vintage crowd and their still-going-strong at fifty-plus years gear.
