The move from dialup rates of 28.8kbs to ADSL (broadband) rates of 2Mbps changed the internet experience markedly from being largely static to allowing streaming video. From mainly textual to a rich multimedia experience.
The new "fibre to the premises" (FTTP) moves up to a potential 400Mbps meaning that a 6GB video disc can be transferred in 2 minutes. Current rates on the first installs are 60Mbps+ - http://www.trustedreviews.com/networking/news/2010/07/22/First-Fibre-to-the-Premises-Customer-Connected---Hits--92-7Mbps/p1.
So?
What sort of tech is this advance in speeds going to bring along? Will we all be using 3D interfaces, will having hard disks at home become a thing of the past, will all application code be delivered over the 'net on the fly? Dare I say ... is computing moving into the cloud?
