I found it interesting that someone at Microsoft thought that it was important to control how guests use the Wi-Fi network and created a whole complicated system of registration and a nice four-color brochure, while the person with the same job at Google just decided to make the Wi-Fi free and open.
Presumably that person at Microsoft was very convinced that all kinds of chaos would ensue if guests just willy-nilly connected their laptop computers to the Internet. And yet Google proves that no such mayhem actually occurs.
