Geo-security: three is now four

The old adage is that there's only three ways to secure a system: something you have (e.g., a key), something you know (e.g., a password), or something you are (e.g., a fingerprint).

There's now a fourth: somewhere you are. Garmin's new Street Pilot c510 has an "anti-theft feature that disables the unit from performing any functions until you type in a specific 4-digit PIN or take the unit to a predetermined location."
