Yeah, I can personally vouch for free wifi access at Philadelphia, Orlando and Atlanta airports; used it at all of them with my old Zaurus. I do note that at some hotels here in TO where I have attended science-fiction conventions, the wifi security obliged you to log in through a webpage that was the first thing up when you opened a browser ... wonder if microB was unrecognised? That could be a bummer, and an added incentive to get Opera running on OS2008.
