One point about the computers... the real value of a computer isn't the hardware, as hardware prices are ridiculously low nowadays. The real value is the data... and some computers will allow you to boot off an external USB harddrive... those can easily be safeguarded by backing up and hiding the external USB drive.
I don't think people are stealing electronics and computers for the data. They are stealing it for the hardware. They don't want your cruising pictures. They want a computer to use or sell.
