That's a pretty extreme measure, though it will give the affected user the satisfaction that the thief that nicked their device won't be able to do anything with it, except throw it in the trash. Samsung will soon start adding the kill switch to its devices in Korea (so will LG, and Pantech has already been doing it since February), as it's mandatory for all manufacturers as part of the “Complete Preventive Measures against Illegal Use of Mobile Phone” act that went into effect on August 13th.
Could we see the kill switch make an appearance on Samsung devices internationally (maybe with a debut on the Galaxy Note III)? It's possible, though for now it seems the addition security step will only be available to Korean users.
