We let our cable subscription lapse. We won't miss it. I never hardly watched it anyway.
We will probably re-subscribe next February when the last installment of Battlestar comes out, then let it go permanently.
A few weeks ago, I was selected to be part of a Nilsen TV survey. I had to track all the TV watching I did in a week.
A week went by, and I hadn't watched a single minute. I felt kind of bad about this because of the survey, but it just confirmed that I was wasting my $$ on my cable subscription.
