I want to install a program for tracing my laptop if it ever gets stolen. I see that the 2740p is compatible with lojack and even has drivers/program for it for free. When I check the lojack website, I see that it is subscription based. My question is for those who do have lojack installed, is it the full version and is it working as it should, or is it a half-baked version? I'm deciding between using lojack or prey.
