There are still plenty of old houses here with a lead water service pipe, and you'll certainly still see plenty of lead used as flashing on roofs and gutters (I have some on mine!).
What I find annoying though is where scare tactics are used to try to make somebody upgrade their house to meet current regs. over some trivial little thing. For example, the fact that the earth wires were not normally sleeved in outlet boxes in older installations whereas sleeving is a requirement now, hardly makes that old system dangerous, does it?
