I was thinking the same.
Been a Telewest>blueyonder>VM customer for many (more than 10) years at my previous address. Recently moved quite a long way for work reasons, and the deciding factor in which house to choose was the fact that one of them had VM cable down the street. The BT line and the satellite dish which were already at the house are now unused. Lead time from ordering to fitting - four days.
I have never had any significant trouble with the cable services, and on the odd occasions that I have (mainly too strong a signal years ago, requiring an attenuator between the modem and the line, and the notoriously bad silver TV box two or three years ago), I always had straight-forward conversations with the folks on the phones, and the engineers have been great. This is in contrast with people who are with other providers (including a friend who works for BT Openzone, who hates the BT service he gets and only keeps it because it is free!)
