I think some people are mixing up lightning protection and surge protection. The former is to prevent damage from lightning directly hitting your house. The latter is to protect sensitive electronics from being damaged by surges of energy that come in through the power lines when the electrical grid is hit by lightning.
I think everyone should have a whole house surge suppressor. Pike’s Electric installed one in my house for $300 a few years ago. Yes, the surge-suppressing power strips could help, but would you have one on your appliances, too? They all have computers in them.
Surges can also come in through your cable. I bought surge suppressors with coax connections for every used cable port in my house.
