I quite agree. Most of what people use the internet for (web browsing, email, etc) is hardly impacted by greater speeds. The benefit is close to zero. I'm still on 1.5Mb/s ADSL. I tried 8Mb/s for a while, but the effective difference, unless you are downloading huge files, is negligible.

Like all computing power, people find ways to waste any resource you give them. No doubt Aussies will saturate the NBN with higher and higher definition torrents of their favourite TV shows and movies, but I'd rather prefer those who really care about such to pay for it themselves.
