Hardly?  I think not.  Certainly compact disc players have reached a point
of abundance where they can count as "common experience."  Also, in this
country it is getting increasingly difficult to find a merchant that does
not use a laser-scanned price code.  Lasers have very much become a part
of everyday life, to the point that often we don't notice them.
