Is there ANY reason to go for wall-to-wall carpet?

The house I now own has gross old carpet that I want to rip out and replace with hardwood or Pergo. The family room and kitchen have a beautiful hardwood floor that has lasted for almost 20 years. I am getting a redecorating bee in my bonnet and want hardwood (or at least Pergo) over the rest of the house. Are there any advantages to having wall-to-wall carpet? At all? [more inside]
