I'm a travel gadget maven, and one of the MOST useful gadgets I've found is my Kensington Wi-Fi Plus wireless signal detector. I took it with me on a recent international trip, and was able to find a wireless signal in places I didn't expect. That made staying online at high-speed much, much easier. It's well worth the USD$29.95 (MSRP) price, and it attaches easily to your computer bag with a keychain loop. Enjoy!
