Getting your laptop stolen sucks, obviously. You have it loaded up with your personal information and data, and beyond losing a valuable piece of property, there's security and identity theft to worry about as well.
With the new Lenovo ThinkPads you'll have a bit less to worry about if it gets stolen. That's because, once stolen, you can send a text message out confirming that it's stolen. The computer will receive it via a mobile broadband modem and lock itself down, rendering the computer useless. While it might not help you get your computer back, it will at least keep your data nice and secure, which is really half the battle.
