I am one of them. Can't believe how Comcast has monopolized themselves in South Philadelphia. No choices. It's the most irritating thing ever, and will most likely make me move to another part of the city (or another city entirely) if they don't shape up.
I live in South Philadelphia (7th and Oregon), and while I have neither Comcast nor Verizon service, it seems like I can get either. They both mail me at least once a week, and occasionally come to my door, asking me to sign up. I investigated signing up for FIOS, but the cost was $90/month, and it just isn't worth that much to me. I have FIOS at work and it's fantastic, but my employer only pays $25/month for it.
From what I understand, Verizon is not expanding their FIOS service area anymore, because so many people are like me, and don't want to pay much for it.
I'm thinking of moving to Graduate Hospital, I don't live in Philadelphia despite the name. Is there a resource to see availability for different parts of the city? I didn't really consider this issue.
edit: nvm the link is the resource, though it doesn't appear to be that accurate of a representation
