To get connected with video instant messaging, you need a Webcam. Here's a quick look at three shipping models.
The $150 autofocus Logitech QuickCam Orbit mounts on an included 9-inch stalk, and it mechanically rotates and tilts to keep your face in the frame when you stand up or move around.
Creative's $90 WebCam NX Ultra perches on the top bezel of most notebooks and LCD monitors. It transmitted crisp sound, and an included headset limits noise pollution. Face-tracking software allows the camera to follow you if you move your chair.
The no-frills $50 Logitech QuickCam Messenger uses the same interface as the Orbit, but it doesn't give you that model's face tracking and other automatic features. Its video quality is good enough for casual use. The familiar "eyeball on two feet" shape will park sturdily on your CRT monitor.
