You are right, t_i_n, except that if Virgin's advertising is to be trusted their claims are closer to the truth because they use different technology to everyone else. One should certainly take the claims of speed with a pinch of salt for most companies though - you won't get the 2MB they advertise unless you're basically sitting on top of the phone exchange at a time when no one else is online.
My advice Ian - unless there is a real need to change providers (if you want to download lots of film, e.g., then Virgin's 20MB is probably worth it), I'd stick with whatever set-up is already installed as far as possible. In my experience, bb providers are basically fine at keeping the line switched on and taking your money every month; it's when things change that they screw up and things go wrong.
