Gave cable up a year ago. Wasn't worth the ridiculous prices Time Warner was charging with their monopoly on the region. (still getting shafted with their internet tho)
I get the regular channels for free in HD through the air.
I use a 32 inch LED TV as a monitor for my computer.
I don't miss cable. I download everything I want to watch... mostly HBO and Showtime shows, and HD movies off of torrents.
I also watch a lot of free mma on the internet. But if there's a card or fighter that I really want to see in HD I'll go to hooters or buffalo wild wings.
I don't really watch any other sports than mma. And the internet has always been the biggest home for MMA.
