Being without cable for almost 3 years...
Basically, if you don't have it (insert your whatever 'specialty channel'), you don't watch it...No withdrawal, no one gets sick, no complain, no nothing. Rogers made it easier for me when they moved The Golf Channel to digital many years ago. I watched almost none since they did it. After picking up HDTVs, all I care to watch are HD programs.
I just appreciate my HDTV more displaying the glorious OTA channels in HD. Love the true call sign for the channels and program info. Sperbowl commercials...No extra boxes...nothing.
