Earlier quoted context omitted.
CenturyLink has finally rolled out fiber to my home (Seattle area). It's taken a long damn time and until they did, they weren't remotely competitive with Comcast. But now I get about 600 Mbps down and 900 Mbps up for $100/mo, which beats Comcast slightly.
What will you do with all that power? I've been on 200+mbps subscriptions for a couple years (in practice at least over 100), and I've never needed more.
Not much. In Seattle, there's no middle ground between 160/10 mbit from Comcast at $80/mo and gigabit from Centurylink at $100/mo. The latter seems like better value, plus I'd like to give a big middle finger to Comcast for their 15 year monopoly in the region.
It does make multi-GB downloads really nice and fast, a few seconds.
