There's small and then there's small: This Bluetooth dongle is less than a quarter-inch thick. People will have to look pretty closely to see that you've added wireless connectivity to your PC with this little guy. Plugging into a USB port, the dongle will let you sync contacts and calendars with your cell phone, and enable your PC to use your phone's network as a modem in case you need an emergency Internet connection. The connector on the microdongle slides out, so as to protect it when it's getting smushed up with your keys in your pocket, making it an ideal travel companion to your laptop. Just try not to lose it, 'kay?
