Pff, TV. I haven't had any channels on mine since I moved here, a year and a half ago. The only thing I can say I really miss is accidently zapping past Simpsons reruns when I'm bored, and ye olde Discovery Channel. But of course, I'd stumble on both while trying to waste time, so the only thing they really do is help people waste time. I don't know, I'm kinda glad I can't do that anymore.
I'm less happy about my 360 still being broken, meaning I haven't even used said TV for many months...
