The WiFi Seeker

There were a couple of credit card-sized WiFi detectors that came out last year,
Kensington's WiFi Finder which turned out to be a dog, and SmartID's WFS-1, which was better, but still no great shakes (though we still use ours fairly often). Anyway, Glenn Fleishman checks out a brand new one, the WiFi Seeker from Chrysalis, which can tell the difference between 802.11b/g and other signals occupying the 2.4GHz part of the spectrum. He says it's the best of the bunch and that it should be on sale by June.
