I haven't really missed tv during my vacation from it. You just fall out of the groove after a bit. You never start to watch the new shows each season and so you never develop a schedule or attachment to what's going on. When you hear people going on and on about Lost or Heroes, you just flash them a look of incomprehension and wait for the subject to change. About the only shows I've followed religiously over the past few years is Stargate SG1 and Stargate Atlantis, and I grab episodes off of bittorrent for that. I can watch them at my own pace, pausing in the middle, and whenever I want.
All that being said, now that the tv is hooked up, I've had it on non-stop. It ends up serving the same purpose as audiobooks. Something to run in the background that I can listen to whenever something interesting pops up and when it's not interesting, just have it drone. Right now I have Comedy Central on and they're playing one of Chris Rock's stand up specials. Spiffy.
