The vendor web sites and "electrician" forums that came up in the google search say otherwise and encourage the use of internal sure protectors as well as the whole house. They don't sell surge protector strips, so they aren't making any money with that statement. They still say that the whole house is MUCH, MUCH, MUCH more important though.
The video I linked above talks a little about using both types of surge protection near the end of it. That mirrors what other information I found.
You are right though. Most people buy a "power strip" thinking that it is a "surge protector" and those are completely different and the price reflects that.
