I personally don't see the need for both. I do see where perhaps paying for cable and satellite has its benefits. There are public access channels available on cable that simply isn't delivered via satellite. If there's a storm that causes signal fade, I can switch to cable. Then if there's a storm that takes down cable lines, I can switch to satellite. Also, at least in my case, it would be how I watch NBC Sports Boston, seeing that Dish doesn't carry it. But, I do have my work around for that. And, that doesn't require me paying for DirecTV or cable along with my Dish subscription.
I would have been singing a different tune 10 years ago. I was more like bluegras. I wanted every channel. I paid for the AT 250 package. I would camp in front of the TV all the time. But, after having kids and some advancements in my career, my television viewing habits changed drastically. Even my handle The Fat Man was due to my being a large man, pushing nearly 300 lbs back then. My diet and exercise habits changed drastically, and that username isn't accurate anymore. I'm not built or skinny. But, I'm not fat either.
