Supposedly only the pentium III returns serial info with CPUID though, and even then it can be disabled in the bios.

A portable super computer, modem, video camera, telephone, address book, flashlight, compass, level, gps/navigator, tv, radio, alarm clock, credit card, ID, library, game console, translator, calendar, calculator, and more. Secured with your biometric information, charges fully within an hour, and runs for about a full day before needing a recharge.

But this one doesn’t fold in half, so I’m throwing it out and buying a new one…
