Will the BT network even be able to cope with loads of people on the new speeds (80/20)? I'm a bit concerned myself, I think they may end up introducing some kind of management to cope with this. When I read it was a free upgrade (yeah, yeah, contract renewal) I wasn't very pleased because of the impact it could have on the network.
Also, it's not looking good for the smaller providers, but a lot of there customers are business users who are already paying a premium for the CS so I suppose they'll probably be willing to pay even more.
