what ever happened to the promise of 'Internet Everywhere?' That's a rhetorical question.... Some of us live in areas with primitive cell service with data prices that are unbearable (**cough** canada **cough**). I don't even own a cell phone because of this so I rely on WiFI. WiMAX is technically here but unusable for us mere mortals. So that leaves only WiFI for me. I've gotten along rather well but of course would love more roaming.
The irony for me is that in canada it is pretty easy to find an open residential AP but harder to find truly free APs, pay services aren't widespread enough. Yet in Iceland I couldn't find any open residential APs but had no problem finding truly free public APs even in small towns.
