Wifi Walker is a little USB key doodad about the size of an iPod Shuffle but with even more focus: if you wander into some open Wi-fi internet, and press the button nicely (I said nicely! It can tell if you're thinking impolite thoughts!) it lets you know how strong the signal is and the name of the network. Simple comme bonjour, as they say over there. No word yet on pricing or availability. [GT]

ZyXel actually has one as well, that's already out. It also doubles as an access point. It's not too incredibly pricy either.
