Sonic only works some places, specifically where there are overhead power lines they can use to route the cables. There used to be some discussion about "microtrenching" so they could cost-effectively bury fiber throughout the city but the Board of Supervisors shut that down pretty definitively (or rather: made requirements that made it too expensive for sonic). So Sonic is really good where you can get it, but you can't get it in much of the city. You also have to be careful, because Sonic has two types of offering: fiber (good) and reselling at&t dsl (pretty bad). Only get them if you get the actual fiber!
