Glen / Ingemar:  CRTs do not contain layer of lead coating inside the
tube.  The lead is contained in the glass and is not readily
bioavailable in a landfill environment.

Today's computers probably do not contain 1/2 pound of lead.
Panasonic's current line up of laptops contain about 5 mg, a long way
from 1/2 pound.

Ingemar,  possibly this article is suspicious because it was written in
1996, long before LCD screens and long before the introduction of RoHS &
WEEE.  CRTs have a heavy layer of lead in coating the inside of the
envelope.  I'll bet that todays lead weight in a desktop would not
exceed
1/2 pound.
