Actally, Bert, the MediaFlo model includes several dozen audio-only
services, semi 'on-demand' a/v 'clip channels', etc in addition to the
traditional 'linear' a/v channels, all of which you need to factor into a
comparison between number of channels.
On the other hand, MediaFlo video is 12 or 15 fps outside of the core
reception zone, and their ability to layer that with 24 or 30 fps in the
core area takes some bandwidth.
"Resistance is futile" is a mantra on Star Trek, not a marketing phrase.
Using it or a corollary in a new medium is "imperial Hubris." They'll be
serving homes, mostly. The question is just how many.

Wrong modulation? All I saw was that it's DVB-H rather than MediFLO
("Impressive early look at what DVB-H can offer in the United States"),
that its performance is the same as MediaFLO, aside from differences
that seem to be only attributable to receiver software (e.g. the
business about having to re-select the channel after a dropout, with
MediaFLO), and that the author of the article wants something different
from the expensive subscription TV he gets at home.
Also, a two-tower transmission system, and a 3:1 better channel offering
than MediaFLO. This suggests, somehow, either much higher spectral
efficiency, a much more efficent codec, and/or less quality per program.
This quote at the end, "failure in this medium is just impossible to
fathom," is just too ironic. We've seen the impossible become possible
more than once, in recent times, after a comment such as this had been
made.
