so the trick is not ditching your device access to online stuff, but your physical access. without a cellphone in big urban centers you'd have a tough time moving around. well, I would.
public transport in big us cities are broken down by little cities, which any European would call neighbourhood... and parking in sf and ny is impractical. now you have to know how to transfer between several buses routes, or even if you decide to just take a cab, you must know the cab number for the company for that specific little region you find yourself at. I can't imagine not having a phone with a browser to navigate this mess, obviously designed to limit mobility.
