Yes. We still want device manufacturers to ground their cases, and using a third wire that is most likely not mounted the wrong way round is preferable.

- marshray 14y agoI agree. It would be a bad idea to have a stack of metal equipment all plugged into floating outlets. You'd be likely to get all kinds of weird voltages between the metal cases. The electrocution hazard was just one way it was the bad old days. It also sucked for other kinds of signals, hi fi, radio, etc. I would not want to try to have a home office full of computer equipment that weren't sharing a common ground. Did you ever have one of those 17"+ CRT monitors? Recall how they would make the hair on your arm stand on end when you turned them off or on? Without a dedicated ground for those things, guess where all that charge is going to go? Into your computer, via the ground on the signal cable.
