If you feel like you're going commando when you're not in the presence of Wi-Fi, strap on this Wi-Fi wristwatch that detects signal strength from 0 to 8, letting you sniff out that broadband connectivity wherever you go. Simply push the Wi-Fi button and it shows you the signal strength right there on its LCD display. It's no Rolex, but hey, it tells you the time just as well. Not bad for $29.99. [Think Geek]
