This is going to be an unpopular opinion, but no, at this point in time, almost no one needs a 1Gb connection. Especially the average home user.
At work, I manage approximately 125 workstations, plus 10 servers and a host of other devices on a 10Mb symmetrical dedicated fiber circuit provided by Time Warner Cable. Our Exchange, FTP, VPN and SSL VPN all are hosted on this connection, plus all of our users. A lot of our network traffic is internal, but we do communicate with our corporate headquarter in Europe via a site to site VPN. A lot of files transferred are larger DWG, DXF, IPT and IAM files. Plus we have a few users who stream Pandora or Spotify and I’ll occasionally stream some How To videos on YouTube. Our network has never been brought to it’s knees in the few years I’ve been here, and very rarely do I hear any complaints about speed.
While we don’t have a half a dozen instances of streaming hi def Netflix going, we do have a lot of people and devices using the connection simultaneously thoughout the business day, and in the early morning hours when our European counterparts are on our network when they start their day.
TWC recently gave residential users another overprovisioned bump in speed. My 50 x 5 connection, is now more like 62 x 6, and I have trouble maxing that out. When 320Mb+ becomes available here I will be beside myself.
