Gadgets, gizmos, and tools to help make you more productive in business

Wifi Walker is a little USB key about the size of an iPod Shuffle. It functions as an open Wi-fi internet finder. Instead of turning on your notebook wherever you go just to find a free WiFi hotspot for you to jump from, why not take the easier route by picking up the WiFi Walker from E-let of Japan? Just press the DETECT button; it lets you know how strong the signal is and the name of the network. Too bad it won't help you crack the WEP or WPA encryption. There is no word on pricing or availability details at the moment.
