I can get "fibre" (FTTC) , but I choose to stay on ADSL for technical and reliability reasons, based on my own experiences working on externally sited equipment. I like to keep it nice and simple, with all the equipment in the exchange kept dry, and fully powered up..
Only my wife and I using the Internet, so the 12Mb connection we get, is more than enough.
Just to add, my first connection, on the same cable, was 500Kbs, which was a vast improvement on dial-up broadband. It then was upgraded to 2Mbs, and now finally 12Mbs.
