It looks like Mac users tired of their built-in webcams and concerned about the clutter caused by regular USB cams will soon have another option to consider, as Ecamm Network has just announced what it's claiming to be the world's first Bluetooth webcam. Apparently, you can expect to get some standard 640x480 H.264 video out of the thing, along with 48 kHz AAC stereo audio and a promised four hours of talk time before you need to pull out that dreaded USB cable. None too surprisingly, you'll also have a pay a bit of a premium over your run-of-the-mill webcam, with the so-called BT-1 set to demand a hefty $150 when it rolls out sometime late in the first quarter of the year. No word on Windows support just yet, but we'd presume that'd follow shortly thereafter, officially or otherwise.
