Give your requirements, Newark would be the best candidate

- EWR close by, with public transportation connections

- Strong local universities, both in tech and business (Rutgers, NJIT, Stevens)

- Newark development is rising, downtown is still relatively sparse

- Audible is already in Newark

Skeptical it will actually happen though. Wouldn't even consider myself a fan of Newark (even though I go to school here), but it's interesting that it's the smallest city on the list population wise.
