It would, except that the spectrum auction model seems to me likely to 
deliver services at a price higher than on fixed BB.

The spectrum is still limited in what it can deliver, especially if we 
ramp up distances, because (a) speed is lower at longer distances, and 
(b) the further you are from the base station, the bigger the beam, so 
you get less re-use of any individual "slice" of the spectrum.

I'm in favour of wireless for the applications it best suits, but not as 
a panacea.

Finally, keep in mind that "we" (ie people of a particular set of 
technical expectations and preferences) remain a minority. Whether or 
not TV is in decline is another debate, but right now, a / the majority 
of people still watch TV.
