"24/7 internet connectivity will be a certainty in the future. We'll have complete global coverage. You'll be diving and able to tweet. You'll be checking facebook on that space shuttle." I question that, or, at least, I question that the quality of coverage will be in the same class everywhere. More likely, coverage will be better in wealthy areas, and not so good—and more expensive—in the poorer ones. So will running networked applications be viable in the poorer areas? It depends on the app and how network intensive it is. The optimism about network apps, everywhereallthetime, has optimism about infrastructure catching up implicit in it, and (for reasons beyond the scope of a deeply nested comment) I don't share that optimism.
