Summary: This camera is built like a tank. It has excellent quality video. My MacMini installed the driver and some nice software, and the little camera works flawlessly with Yahoo messenger. I bought the little camera brand new in non original packaging for $42.00 bucks shipped and I couldn't be happier with my purchase. Apple got it right with this little USB Webcam. Just plug it in and start using it within a minute or two right out of the box.
Summary: I really like the iSight. You need a Firewire 400 port or an adapter if you only have Firewire 800. The package includes 3 types of camera mounts. Setup is very simple - the camera features automatic focus plus a noise suppression microphone using just one cable for power, audio and video. Needs a DSL or faster Internet connection. Compatible with my late 2009 Mac Mini running Mac OS X 10.8 and many other models and older OS X systems.
Summary: This camera has many things that make it worth the consideration to buy. It feels sturdy upon holding, and has actually fallen off of a low shelf on to my desk with no damage or marks. I appreciate the hardware version of turning off the camera, as I do see why people might like that better. You can simply twist the aperture shut, and not worry about any security threats for example.
