I got rid of all the TV stuff nearly a month ago; initially I would still think 'I'll go and veg in front of the box'...' then realise it wasn't there ! I now find I'm actually doing a lot more productive stuff than before (no surprise really).
Like most people, I used to veg in front of the 'idiot lantern' in the evening.
I have 'rediscovered' radio; there are plenty of interesting broadcasts on that, apart from the usual music channels. I personally find the PC also provides more information than the TV. I've still got my CD player etc.
It will interesting to see how long I can carry on without it. It's almost worth it just to see peoples reaction when you tell them you haven't got a TV; the poor creatures are hooked on it.
However my neighbour has announced he's getting a 36" flat screen, and gleefully tells me he's been watching RM etc....doh!
