Hardware Pacers has posted a review on the Microsoft LifeCam NX-6000

Microsoft's LifeCam NX-6000 is a nice little webcam, but may not be all that a user may expect. The NX-6000 is a high resolution webcam with 2.0 mega pixel video, but the quality of the video is not all that it would seem in some of the resolution settings. At 640x480 and 800x600 the NX-6000 performs marvelously, but other resolution settings are not as nice. At higher resolution motion is blurry and distorted due to low frames per second, while at the low resolution settings the picture is out of focus.

The video quality settings are an issue, but the design of this camera is amazing. Very small and portable, with a retractable lens. Once the lens is out it has the ability to tilt up and down for the perfect angle. This camera is perfect for portability; it is rugged and the lens is protected. The camera clip on back is quite sturdy as well. In addition to all that, this camera comes bundled with a nifty carrying case.
