Driven mainly by Infinity fibre rollouts, they're one of the least latencied connections going so far.
I had meant to say that I am keeping an eye on BT and the impact of their 21CN on their network. Theoretically it does have the potential to remove at least some of the colossus issues, so I do agree with your point of view to some extent.
However, if you look at other aspects of ISP operations, such as Customer Service, dealing with BT's far-east callcentres is like pulling your hair out, in comparison to dealing with ISPs who have reasonably on the ball people sitting in the UK.
Also, you have to remember it's early days for Infinity. Will be equally interesting to see how things look once the legacy DSL customer base has eventually migrated over, and the old contention etc. kicks in.
As the old saying goes.... I'm reserving judgement.
