That kind of business cable is available here [Winnipeg Canada]
for about 1/8th of the price of a T1 -- less than $US100 compared to
about $US1000 for T1. 10 megabit burstable fibre has been available for
years here for about $US250. And yet there are still quite a few
T1 providers.

People around here don't buy T1's for -speed-. Reasons why they
do buy T1 include:

- T1 provides symmetric bandwidth (SDSL is not very common here)

- T1 is point to point and thus does not have the security issues
that one has when one is connected to the Internet

- T1 are available -most- places that phone land-lines reach --
the required infrastructure having existed for long enough for
very good saturation.

- T1 do not degrade with congestion from other users on your block
(a significant problem with cable!)

- T1 have fixed latency and bandwidth, not variable as cable has

- T1 is synchronous and thus suitable for multimedia applications
that degrade when frames are received out of order

- T1 has no bandwidth caps, content filters, forced http proxying,
