Jawbone Era

As if we didn't look dorky enough with Bluetooth headsets in our ears, along comes the Jawbone Era ($130) to kick things up a notch. Packing the company's chaos-killing NoiseAssassin technology, improved "HD" audio, and a processor for running "apps" like the new spoken name Caller ID, the Era also sports an accelerometer, letting you shake it (or your head) to enter pairing mode, and — we're not making this up — "tap" it to answer calls, meaning you can now smack yourself in the side of the head before appearing to talk to yourself in a public place. Gotta love progress.
