As a former engineer for a cable company for 10 years my view may be somewhat myopic ... but you are very misinformed. The ONLY competitive advantage/business model advantage that satellite has over cable is that they are not subject to the same federal/state/local taxes that cable is. In fact, satellite's business model lagged far behind cable's, as satellite persisted in charging for equipment and cumbersome contracts, all things cable abandoned long ago. Don't even get me started on service call fees and local channels ...
The bottom line is you get what you pay for, if you are comparing a cable bill that includes premium channels/DVR/HD to a basic package satellite bill is the ONLY way you are going to get a satellite bill to be 1/3 of a cable bill. For similar packages/services, you are going to pay a similar amount, because the price of programming is controlled by the networks you are subscribed to, not by the cable/satellite provider.
Sorry for the thread hijack, but some old habits die hard.
