I was just skimming through my new Tiger Direct mail-in catalog and noticed on page 13 that they are selling a laptop called the Lenovo IdeaPad. (Lenovo what used to be IBM's desktop/laptop division.)
Well, anyway the laptop comes with software called VeriFace which uses the embedded 1.3 megapixel camera to scan your face. It says "Make your face your password!" and actually has the gall to fawn over how cool the feature is.
It doesn't have any information on if the VeriFace software can be uninstalled. If it's actual software, then it can probably be uninstalled. If the software is installed on the motherboard (like on a ROM chip), then it cannot be uninstalled. And if the software is installed on the motherboard, then there might be a chance that it will not allowed alternate OSes (i.e. Linux and BSD) to be installed. VeriFace is included with this laptop.
