Newsgroups give me 6.6Mbps download on 50Mb.
The infrastructure is there if you have a need for it, it just depends what you use your connection for. I still find it amazing though that some people get faster broadband because they think it will make web pages open quicker...
The reason to introduce 100Mb is obvious, it will help push demand for applications that CAN utilise that kind of bandwidth. If we dont have it then we dont know what we can do with such a fast pipe into the home. The possibilities for an ISP with a connection speed like that are endless, with online TV being the biggest reason.
