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.
