In terms of computers (including PICs), I don't think it's a
question of IF they will crash, but more a question of WHEN they will
crash.  Having a WDT allows the system to recover from the crash.  I once
had to drive 100 miles through Kansas in the middle of the night to hit
reset on a system I built to control broadcast transmitters so the
station could go back on the air at 6am.  EVERYTHING I've built from then
on includes a watchdog timer...
