Bluetooth


The promise: This wireless technology connects your wireless headset or speakerphone with your cell phone for hands-free talking while you're in the car or walking down the street. Bluetooth is also used to blast out music from your computer in stereo to wireless speakers or headphones up to 30 feet away, or wirelessly transfer pictures from your camera phone to a Bluetooth-enabled printer or computer. Bluetooth-enabled computers can also sync up wirelessly with Bluetooth-enabled mice and keyboards to reduce desktop wires and clutter.

The reality: Synching up your gadgets -- called 'pairing' in Bluetooth speak -- is an often cryptic process involving pressing different buttons simultaneously, then entering a password so that two gadgets can "talk" to each other. Bluetooth gadgets are then supposed to stay paired forever, even if you turn off one of the said Bluetooth gadgets. Sounds wonderful, but if you've ever used a Bluetooth gadget, you know that pairing (and staying paired) just isn't that simple -- gadgets stop "talking" to each other for no reason, despite registering as "paired," and some Bluetooth gadgets just won't talk to each other, with no explanation for the average user.

Bottom line: We recommend IR- or 2.4GHz based keyboards and mice, if you want to go wireless. For headsets, Bluetooth is the only option, unfortunately. For everything else (camera phones, printers, etc), make sure you also bring the appropriate cables and wires just in case your Bluetooth goes on the fritz.
