I am another weirdo luddite - no TV, no mobe, no microwave etc (I can't be a**ed with a heart monitor, GPS or whatever either). I grew up without TV, as did my wife.
I have to say, I don't violently object to TV, it seems to have a fair few good things on it [eg Blue Planet, Jane Austen dramatisations], a lot of which ultimately get marketed as videos [Hildegard, next time you're around, come on over!]. We do have a video machine, which I guess is an expensive way of managing selective TV watching!
Trouble with TV for us is that it becomes the focal point of the main room in the house (and placed in front of the most comfortable chair), and it must require a lot of self-discipline when you're tired after work not to flop down and just goggle.
You do miss out on a fair bit not having TV - I often couldn't follow other kids' conversations at school, and I guess the same must be true for my kids. Also, I literally can't follow the speed with which the images change on some programmes.
I remember Camille Paglia saying that anyone who doesn't have a TV doesn't have the right to comment on contemporary life and culture - while that may be a bit extreme, I can see her point, you are removed from something that is the major cultural medium for the vast majority of people.
I cheat when the rugby is on and I haven't got tickets, find a pub or someone's house with a TV.
