One-way or Two-way satellite for rural areas, but most are getting cable modem and DSL access too now.

For Cable and DSL, yes, I think so. For modem, the higher priced ones ($19.95+) is too much. Technology cheaper, but people still pay the same price or even more as 5 years ago. Satellite service is new, so it'll be costlier too until more people will sign up.

Well, most residential areas have access to low-cost high bandwidth connections. Rural sites may have access to the satellite services, but they don't come cheap. With prices for cable and DSL access dropping, it's becoming more popular to have broadband access instead of modem access.
