That sounds utterly unappealing. If I'm in a coffeeshop I have zero reason to want to cut off from the outside world. Otherwise I wouldn't be in a coffeeshop. Most of the reason I'd work in a coffeeshop is for an ambient social vibe. And for many things I do a 13" laptop screen is fine. (And I probably wouldn't feel comfortable being utterly cut off from the environment in an urban space.)
