Truth is, once the user is achieving what they consider to be acceptable performance they don't care if it is symmetric 
or not.


Not a very informative discussion.

Points of fact...

>From Verizon's January filings regarding 2014Q4:
1. Verizon has about eight million FIOS customers.
2. "Fifty-nine percent of FiOS consumer Internet customers subscribed to data speeds of at least 50Mbps, up from 46 percent 
one year earlier."

Eight million FIOS customers does not even come close to representing the bulk of users out there.  In fact, it does not even 
represent the majority of "high speed" customers out there.

>From a Verizon press release last summer, all FIOS speeds are now symmetric.

And no one cares.  I don't even see Verizon commercials crowing about how great it is to have symmetry.  If customers loved 
it that much don't you think they would market that way?
Hi Steve,

I live in the Tampa Bay area and I see Verizon commercial all the time where other ISP customers are complaining that 
theirs ISP take so long to upload pictures, backups, etc.
Plus there are commercial with people on an escalator where the up escalator is much slower than the down escalator and 
people are complaining up should be as fast as down.

Regards,
Steve

ADSL development proceeded the development of the consumer Internet. The original patent was filed in 1988. DSL was 
designed originally to deliver video in an ISDN/ATM world. For that reason, it was asymmetric.
ADSL did not proceed the development of the consumer Internet in the commercial world.  If it did, we would never have 
gone with dial-up modems.  Patent dates have very little to do with commercial availability at all.  Please give me an 
example of a purchasable service using ADSL prior to its use in Internet delivery.  The number one reason ADSL 
succeeded and SDSL did not.....you could put an ADSL signal on the phone line you already had in your house, SDSL 
required a new loop to be ordered.  Faster to provision and it can be done without a truck roll.
