I have all computerized machines. I am not paranoid about storms and have no surge protectors and don't unplug. I always go on as normal during a storm. I remember as a child our house having lightening come in from an open porch door, go around the baseboard, and out the other porch door. My DGM was screaming and DGD and I thought it was neat. I really would not rely on a surge protector. I have heard they fail often. We have a gadget before our electrical box that is suppose to stop surges of power and it seems to work. It was installed by our electric company.
I am one of those crazies that likes to watch storms.
