I've been using the FTTH (Fiber to the Home) internet speed since 2004 when I was in Tokyo.
I moved to San Francisco in 2006 and used Comcast for just a few weeks and found that my apartment building has a better option, webpass that provides a shared FTTH 100 Mbps up/down and have been a happy customer since then.
Next week I'm moving to a new place, which is actually just a few blocks from the current place, but the place is not the lucky one that has webpass installed. I contacted webpass sales, and while my new landlord agrees to install the service, webpass claims that I need an approval from Home Owners Association at the new place that the majority of the tenants/owners would use it as a primary service, which might be possible but would take time.
So for now I signed up for sonic.net fusion. It's an ADSL 2+ service with unlimited landline voice, priced 20Mbps for $50. Not terrible, but it's a huge step down from FTTH that I've been spoiled for 7 years. I really wish sonic.net moves on to the fiber development soon, or that HOA approves webpass or Verizon FiOS coming to SF.
