There is still an issue with the lead-free solders, which is why in anything that must be reliable lead solder is still used. That includes pacemakers and space satellites.
And of course that old warning still applies, even with lead-free electronics: "never pull parts off the circuit board and eat them." They are still bad for one's health.
