So you’re at the coffee shop, and you’ve walked over to the counter to order another half-frap-double shot raspberry no fat mocha, and left your iPad (or iPod) plugged into your laptop.

You don’t see him because you were looking away, but you still know your kit has been boosted! How do you know? Well, you had the PadLock installed.
