I'd sign up in the most prone season - to weather-related blow-out - as long as signing up is also conditioned on full-money back or opt-out if the Net system is not accessible during, i.e., storms.

Then, again: It is not wise or prudent to keep a computer tied to any outlet (powersurge or not) during storms; doing so does have the potential to totally wipe out a hard drive; it can fry out.

If someone has a computer/hard drive that can withstand possible frying for a "test," I'd go for the satellite setup.
