FTTC is a pitiful enough attempt to appease the masses
The ideal would be ubiquitous FTTP, but that's roughly an order of magnitude more expensive than the predominantly FTTC roll-out we have got.
FTTC roll-out takes fibre deeper into the network, which is enabling for future deeper fibre systems (including FTTP and FTTDP).
FTTC delivers considerable speed boosts to many users at a price many UK consumers are willing to pay. For a small extra monthly amount, I've gone from 16/1 Mbit/s ADSL2+ to 80/20 Mbit/s FTTC, which makes a significant difference to my increasingly cloud based Internet usage. That said, I recognise that I'm fortunate in the FTTC speed lottery, living relatively close to the cabinet with a decent D side pair.
FTTC that falls into the superfast bracket (>30 Mbit/s downstream) is good enough for most current residential usage scenarios. Indeed, if I understand MrSaffron and other posters correctly, those with ADSL2+ speeds close to the maximum possible 24 Mbit/s downstream speed often choose to stick with the ADSL2+ service they have rather than paying to upgrade to FTTC.
There are always those who have a usage scenario that demands higher speeds than Openreach can deliver to their property. As I said, I'd love to see ubiquitous FTTP - but I'm a pragmatist. It's better to have what can be afforded now and recognise that it lays the foundations for future deeper fibre.
I'm very grateful Openreach have rolled out FTTC in the area where I live, rather than leaving us waiting whilst they tried to justify raising the money to bring FTTP to this predominantly dormitory town.
I'd certainly take FTTP if offered it at around the same money I'm paying for FTTC, as I'd love to be rid of the vagaries of RF transmission over unshielded twisted pairs. However, 80/20 Mbit/s is more than sufficient for my needs at present. Few can justify a large premium to get a similar service via a more robust and future-proof technology.
