The rule is
NOT "ten years". The rule might have been "ten years"
sometime in the early 90s, but a longer period has and is being
gently and gradually phased in. Ever since the early nineties,
increment the rule each year. ... Therefore, the current rule would
be somewhere in the mid to upper 20s years.
Everyone should through the
"rule" into the trash, because it'll
always cause these dumb arguments and always have exceptions. Just
use common sense. Nobody wants to discuss 386s here, and anyone who
says "Windows" should be shot.
