It's just bizarre. I use my broadband connection most days, and for working from home. It costs me less a month than the price of a round of drinks, a share of the food bill and a cab home.
I am not happy about a few things to do with VM, I would love it if I could pay extra to boost my service to 20/2 or 20/5, I dislike the congestion, I dislike STM. At the same time I do,
to an extent 
understand the quandry.
I would still, however, very much like to know how much profit Virgin make on broadband
