Thanks for all the replies.

So ADSL is a technology developed to cope with the installed
telephone lines, not a technology developed independently and then
shoe-horned onto the existing lines? This makes much more sense to me
now!

The one thing that annoys me about cable is the asymmetry of upload
speed compared to download. I have a 60 meg DL, and 3 meg UL. I do
enough uploading for this to be a bit of a pain in the arse!

Well that's better than any ADSL setup...

ADSL seems to have MUCH better upload speeds. As I understand it, it
is due to the bandwidth allocation of the cable system (DOCSYS?) and
the 'traditional' bandwidth requirements of earlier consumer internet
times.

The A of ADSL is the key! Typically most links will top out at about
1Mb/s upload even if getting the full ~24Mb/s download.

VDSL (i.e. FTTC) will do a much better uplink at over 8Mb/s

There is also SDSL (symmetric) available in some places (usually at much
higher cost) for those that need the outbound data rate.

I wonder if we'll ever get a Google fibre style company in the UK?

Who knows... IIUC they have bought up loads of unlit fibre for future use.
