The reason that it's such a debate in Australia is that, even though
these things are all known, the NBN has become a political badge. Roughly:
Want fibre = ALP supporter
Wireless is sufficient = Liberal Party supporter
This gets pumped along with "Wireless is getting better all the time,
who knows where it will be in ten years?"-type statements. (Correct
answer: still behind fibre, because fibre research will also continue,
but who cares?).
It gets further pumped along by statements from "business leaders" (eg:
Graeme Wood, Wotif, today anyhow) taking the "fast broadband is not for
consumers" line. It's unimaginative in the extreme - Wood, for example,
merely listed today's apps and said "so what's the point of just doing
this stuff faster?" without any consideration of whether new
applications might arise.
