It's not for you. It's for, as said above, businesses who would normally be getting a carrier-grade circuit from a telco. If the business is in a Cogent-lit building they could get 100 Mbps symmetric for $600-$900, Comcast beats that, though the upload suffers.
Looking forward to upstream channel bonding that'll make higher upload speeds possible. I don't ned 100 Mbps either, but the extra upload speed is welcome.
