I always do! Always. I had two modems zapped through the telephone, and not even from lightning in my close area, but from a remote strike at another phone switching station.
I unplug and stay unplugged for a long time, because there can be stray electrical sparks in the humid atmosphere. I’ve had that happen, too - an hour after any lightning. A “dry” electrical storm with no rain.
I never heard about it before I ruined my computer. I am surprised so many people know. I brought it up once on a FR “computer” thread, and, like you, everyone said...oh yea, I unplug my computer! lol
