It's all crap
I live about 2 miles from a Telewest/NTL/VM in Basildon and our whole estate doesn't have cable, even though the rest of my town does.
So, I have Sky and the broadband is not bad. I only took the SkyTV because it was the same cost for the broadband+SkyTV as I was previously paying BT for just broadband.
A friend had cable but he switched to Sky due to repeated connection problems since Vm took over Telewest/NTL.
He's pretty happy now.
As for the TV, well, from what I've seen you have a choice of hundreds of channels of shite on VM, or thousands of channels of shite on Sky.
Personally I watch motor-racing (F1, MotoGP, WSB, BSB), TopGear, and the rest of my viewing is "filler" mostly taken from the Documentary channels. The Missus watches BBC1 & ITV and could mostly care less about the rest of the shite.
So, what has the TV "revolution" brought me then?
Well, I can now watch the bike racing on TV.
That's it, nothing else.
From my point of view the whole "revolution" has been a total waste of time, money and resources.
