In either case Kill Switch is a misguided effort in reign in theft, there's no Kill Switch on laptops, wallets, you-name-it but they get stolen just as often.
If you could remotely lock-out your laptop, wallet, phone, tablet, you-name-it, their theft value would drop drastically since the risk of getting caught fencing stolen good is much higher and the value of stolen goods also becomes much lower: what are the thief's chances of selling a stolen phone or tablet if the devices display a nice little "This device has been reported lost or stolen and is currently locked-out" message when people attempt to turn it on within minutes of being reported lost/stolen?
The device becomes practically unsellable even for parts if the lock-out gets propagated to all components with built-in microcontrollers.
