I use a television but it functions primarily as a large computer monitor, my mac mini is the primary component. Most of my watching is done via streaming these days; Netflix, Hulu, Amazon and direct from network websites. I split my internet bill with my roommates and I pay for Netflix streaming...cost is less than $20 per month. I get free broadcast HD channels with a rabbit ear antenna but I almost never watch things that way, I usually wait until the next day and watch on Hulu where there are less frequent and shorter commercial breaks.
Haven't had cable TV in years and don't miss it at all.
