Australia is not the first to do FTTP. You don't have to wait, its already available in many countries.

You can also look at how much people valued the additional speed, what new things they did, etc.
Wish someone would write an article summarising the overseas experience of FTTP.
Also, what is opportunity cost of NBN? Could we spend money to create a high-tech sector in Australia perhaps?
The ALP tend to use the NBN as a catch-all for tech policy - "don't worry we have innovation covered - its all the NBN".
