Sad to say, I'm very pleased
My local BT exchange is some 3km distant and at best I could only achieve 3Mbps so my only choice was VirginMedia's 20Mbps package.
Speeds were rarely as advertised, varying between 10 and 20 Mbps and an abysmal 750k upload. When BT offered me the new Infinity (FTTC) package and estimated 17.7Mbps download and 6.9Mbps upload for my personal installation, I jumped at the chance - even if they are half that, they are not much worse than Virgin on the download, and infinitely better on the upload. The package was appreciably cheaper too.
One week after installation, download is 30Mbps and upload 8Mbps consistently. Support is in the UK and I even had a call to establish whether I was happy with the service or not! It's been a long time coming, but BT do seem to have got it right in recent times, despite struggling with a fundamentally antiquated network, and it now has a new, very happy customer.
