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.

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.
