Security is often accused of making things less convenient, but this is absurd.

You might think this would stop shoulder surfing, but in fact if someone was going to do that they'd likely be doing it from off to one side, and as this photo demonstrates, the handle obscures less from such an angle. It's greatest impediment is to the person standing directly in front of the lock.

In reality I'm sure this computer can be cracked. It's probably not the unique and special snowflake it appears to be and so it's weaknesses are probably known.

If it is unique, however, then I don't think Shannon's maxim would apply. How could the enemy know the system if there's only one system and they've never had access to it?
