This is an interesting article about television usage in America. More and more people are getting rid of cable and satellite, but they aren't getting rid of their TVs...
"Many of these homes are satisfied to use their TVs for games or get programming through DVDs or services like Netflix or Apple TV."
I'm not quite ready to go there yet, because I still like watching live news and sports, but I can see a day in the not too distant future when I'll be perfectly happy watching those through the computer.
