Well, i will leave my inteligence alone to myself.
I was refering to the "10Mbps" that the article refered.
In case you don't know, I can inform you that there are plenty of people that would be happy to have 5Mbps in UK.
Actually there are areas, like Island of Dogs in London, where you are lucky if you get any connection at all, just because the phone exchange is overloaded and there is no more capacity on it for years.
So yes, there are issues, and yes, internet in UK is crap comparing with other civilized countries.
Now regarding the cables not supporting, depends on the cables.
In case you didn't know either, some areas have cables not of copper, but of aluminium (which was way cheaper at the time, and worked for normal voice, but it's %£%£$% for internet).
So your milleage does vary a lot.
