Great to hear this news, and to see LLU and Infinity combining nicely. I'd love to clarify a couple of things though.
1) What is TalkTalk's pricing structure for these products? Is it, as the TT website implies, £10 for 40Mbps or £15 for 80Mbps? Or is it, as this article states, £10 for 40Mbps and a further £15 (i.e. £25 total) for 80 Mbps?
2) Also, if they're offering an 80 down/20 up product does that mean that their 40Mbps is now 40 down/10 up (as per BT)? So far TT's offering has been a paltry 2Mbps upstream.
The TT website is unhelpfully opaque on these vital issues. And this article doesn't help to clear them up as it stands.
The devil is, as usual, in the details (and the customer support).
