The future is satellite. Wi-Fi will just be a fad like the laserdisc.

Wi-fi is already much bigger than the laserdisc was and it's growing
exponentially. The laserdisc died on the stores shelves from the
gitgo.

Probably not - that is, if we're talking about customers directly
accessing the
satellite.

It's the cost of consumer direct access to the satellites which is the
show-stopper and I don't see it coming down to dialup costs for years
if ever. 80% of the U.S. consumers with access are still using dialup
connections and most of 'em are not going to move to broadband until
the costs get a lot closer to dialup than they are.

While there's definitely a future for satellite comms, the
"last mile" problem combined with the enormous bandwidth of fiber
limits its usefulness as a general-purpose broadband access method.

Say you orbit a new, state of the art satellite. How much bandwidth
can it provide to how many customers?

A whole bunch. Even the old birds which have been up for years can
repeat something like 900 TV channels and those are not considered
high-capacity satellites.

Compare that to what is
available in a single fiber. Also remember that once the duct is in
place, pulling another fiber isn't that expensive, and that new
technologies permit more bandwidth in existing fibers.

What "ducts"?? There aren't any ducts running into farms and vacation
lodges out in the boonies. They'll have the last mile problem for
years to come. Until the phone companies replace their twisted-pair
wiring with cable, fiber optic and otherwise.
