Let's not forget the middle ground, a "pizza box" that sits on the roof and provides 1Gbps wifi connectivity to a home is something that rents for $50 a month to hundreds of millions of customers, while the $15 version - to a billion customers.
Aww, hell! Make it a small pizza box sized device I can put on a bracket I can hang out the window! Include a wireless hotspot and you'd sell those things like crazy!
BTW existing US regulations on apartments and the like require landlords to install roof antennae if technically required.
