This webcam is our latest (2010 Dec 10) acquisition and is nice in its combined audio and video in one usb package.
The resolution comes up as 1280×720 and looks quite nice. There is a problem however. Whenever this camera is plugged in, no other usb device works, ie usb flash drives, canon powershot A540, etc.
Big drawback. Imagine using video skype and then plugging in a usb flash drive to bring up some files… whoops! no you can’t!

Updated: this was only true on a specific computer. When moved to another it no longer seems to mess up.
