It is a shame computers don't have a key of some sorts today. Imagine a small sim-sized key that had a vital circuit on it and was removable. Going for lunch? Leave the laptop, take the physical key.
If you could use the key to also make it bypassable by your phone's Bluetooth the key need not be carried around. Anyone stealing it would never be able to get in. If the only way to get to the bios was with the private key on the physical key then it could be rendered useless to a thief.
If this physical key locked the screen of a laptop to a keyboard that would make a very effective 'key lock'. It is a shame the keylock did not take this evolutionary path.
