OCC has published a new review of the Logitech Quick Cam Pro for Notebooks

Not wanting to only compare the QuickCam Pro to itself, I also fired up the iSight on my Mac. Although there was no software installed, the Mac picked up that there was a camera and set it to be used as the default inside of Photo Booth. I took image captures at the default settings since I was unable to alter the settings on the Mac. As can be seen, the image quality of the QuickCam Pro is a lot better. Colors are more vibrant and video is smoother. This lays waste to the built-in competition without looking back. The first one is the QuickCam and the second is the iSight. The flash from the Mac's software hurt the image quality a little on both pictures, but they are still pretty good representatives of the type of quality you would get out of them.
