"So you've got the latest WiFi-capable smartphone and a Nintendo DS Lite with you, and you're itching for some gaming session with a little email on the side. How are you going to find the nearest WiFi hotspot in order to get going? That task is made simple with this $18.95 pen that comes with a built-in WiFi finder." - UberGizmo
