Here's the problem: only one provider in the US with any sort of footprint (sorry Paxio) has turned on 100 Mbps service as of right now. Comcast's 100M trial doesnt count yet, though it will later this year.
Ouch! But true enough. Even when Paxio fills out the S.F. Bay Area they're never going to rival the big cable incumbents in total size. But if you're lucky enough to live in Paxio territory you suddenly have CHOICE.
