Expanding WiFi hotspots

Interesting story here about Mickey D's offering Wifi at some of their resturants. It says that they plan on charging $4.95 for 2 hours but as an intro will offer it free with the purchase of a value meal. I predict they will never make money at $4.95 but if they continue to offer it with the purchase of a value meal, which I think they will find is the only way to do it, it will be fine. I can see popping open my laptop to check email but to spend 2 hours in the golden arches trying to do actual work, no way.
