(Sorry about the mini-hijack, Ron)
Josh, I tell the guys here that just locking his PC every night is like staying at work, but with the lights off. Logging off would be like staying at work, but napping. Restarting is like going home for the night to return the next day, refreshed, but shutting down would be like going home and having a nice long sleep.
.........I know... over-simplified and far from acurate, but I'm just trying to get him to restart his machine every night.
