Fernando,

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.

sigh.
