I have given up on most TV - especially cable TV. Almost 3 years ago my wife and I moved and decided to not startup cable TV. I setup an antenna and run MythTV, Boxee and anything else that will run on a browser + flash. I run a virtual machine for Netflix. When we started this experiment, I thought we might go running back to cable. What we discovered is that there is a ton of content available. The Mythbox nicely removes commercials.
When people hear that I don't have cable, many are confused that I can receive HD programming over the air. The cable companies have done a brilliant job confusing the public into believing that you must have cable to watch TV and/or access HD content.
We couldn't be happier. I challenge anyone to give up paying for cable tv. Good luck!
