Was pointed to this little gaget on a email list at work.  This has got to be a must have for any global mobile worker.

I have often been wandering around airports and cities wondering where i can get a Wi-Fi connection.  This little key ring gaget provides a direction and strength indicator to Wi-Fi networks.  Does not indicate if they are secure or not however.  So no more running around looking like a shady hacker with your laptop on a busy street!
