I keep a pretty close eye on the industry (as a lot of folks here can attest to), and generally, everyone raises rates. And you're not losing channels, but rather, cable companies are adopting the satellite service's model of requiring a converter box for higher levels of service. Those channels are still there -- you just have to pay more and deal with a box to get them. But that's always been true of the satellite services. In essence, the satellite services, by engaging in this "more HD channels" war, have forced the cable companies to become just like the satellite services.
So if you'd like a change to satisfy personal frustrations, then surely switching to satellite is a good move. However, overall, and in the long run, there won't be a significant difference in your experience, on average. You'll just have someone else's systems and processes to learn.
That's not the say that specific individuals wouldn't be better off with one service versus another. Rather, just that overall, the services on average are comparable to each other, for the price each charges. So to determine whether satellite would be better for you, you need to solicit advice from people who are just like you. Otherwise, you're getting advice from people who may be better off with satellite, even though you wouldn't be.
I agree, the industry as a whole is horrible. The only time we had outstanding customer service and reasonable rates was when we lived in our old town and there were 2 cable companies in town-imagine that-competition can do wonderful things. Our switch was after 2 months of no internet and the cable company dragging their heals, not being able to find the cause of the issue=wanting to dig up our driveway to lay new cable lines when the problem (which I told them from the start was the modem, which they never tested) was the modem-simple, easy fix that turned into a 2 month battle. I even got a call from the President of the cable company asking how he could remedy the situation. I told him the only way I would stay with their company is if I got free cable and internet for life. He didn't give me that so we had Dish and DSL installed.
