The letter is very one sided, you don't have fibre optic to house, so this presents a big issue to the claims they make.

One thing to note. According to BT themselves, 21CN is only replacing the networks that link the exchanges. They will *not* be replacing the lines to the users. So, 21CN will have the same pros and cons that ADSL has.
In essence, the user may see little or no benefit from 21CN. Admittedly, we may see an increase of premium services, such as BT's movies service.
However, the complexity (and therefore costs) involved in BT's own systems will be massively reduced. Whether they pass those savings on to the customer or not is another matter.
