I gotta say this app strikes me as totally unnecessary.
You pay money to a company in the hope (?):
that your computer will be stolen (insurance would cost you about the same amount and it will actually guarantee you a replacement),
that the person who stole your computer is so utterly incompetent that they do not know what the camera light on the computer means,
that the thief has no idea about this software, and is again too incompetent to turn off the wireless or wipe the drive,
and, that the thief somehow has the ability to steal the computer, but somehow lacks the ability to actually unload it for money,
I think this is a blatant ad created to drive business to the site by scaring / pretending to empower people.
