WiFi vs 3G at Panera Bread

This GigaOM article answered some questions I have had about how people access their increasingly large datastream. I always use WiFi at home and have helped several people set up their own secure Wifi connections. I was further struck by the discovery at Panera Bread that they had instituted a 30 minute maximum access to their WiFi. Foolish of them since I can get unlimited connections at several other restaurants nearby, where I am likely to move my meetings. Yes, I know and have observed that people hog their Wifi. Yet a simple upgrade would solve their problem and ensure their customers staying around. Foolish move. The post above talks more about how people are using and expecting Wifi in their environments.
