Yah yah, I think NTL are decent tbh, been with them since the 64kb days for broadband, and tv since the beginning. Very rarely have things gone wrong, and been sorted when they did
As for the upgrade, I see nothing wrong with NTL doing what they are, and if they get a load of people upgrading to get 10mbit early, then good for them.
As you've said saxo, they're the only decent providers available.
(p.s. I don't know fully what all the upgrades are doing, Im assuming everyone will be on 10mbit? with strictly enforced download limits? Anyone know what these limits are?)
