The 'Free Public Wi-Fi' network you might see listed on your Windows PC when you're in various public places is the result of an old Windows XP bug that causes the OS to set up an ad hoc data-sharing network for connected PCs if it can't connect to a trusted wireless network automatically.
Connecting to this type of device-to-device ad hoc network rarely poses any immediate danger, but it won't get you onto the Web, either. And malicious users could spy on the connection and steal valuable information from you.

It also reminds you of how powerful personal computers of all shapes and sizes have becomeand that thought alone might make everyone a little more tolerant and patient when problems arise.
