What Fletcher Wrote, in spades. 

I will wager that most residential customers have never heard of symmetric
speeds. I also will wager that they would like to be able to send large mail
faster, upload to Yahoo! and other web hosting services faster, and so on. I
know that *this* particular Cox Business customer would like faster uplink
speeds, and doesn't see 20 MBps in either direction on the best days; since
this is the threshold for "broadband" according to Uncle Charlie, Cox is not
providing me "broadband" service.

Before I got into this, I "owned" large to very large IBM mainframe computers.
There *always* was latent demand for bigger and faster, much the same way an
Interstate highway, on the day it is opened for service, is *always* over its
design capacity immediately, on the day it is opened.
