So sometime last year I had bought a Surface Pro. I never had any issues with it and I loved it, but it was stolen. I was such an idiot and I can't believe I had misplaced it. Recently I purchased a refurbished Surface Pro that was $500. I wanted a Surface Pro again so I could have a device that was mobile and that I could use to draw on. So here is where I need help. What are your suggestions for anti theft apps. The only one that I know of is Prey. The other thing is I heard that the only way to track a stolen tablet is if it is connected to the internet. So I was wondering if there is some sort of gps chip that I could buy and possibly attach the tablet that I would be able to track without it being connected to the internet. Any and all help is appreciated, thank you very much.
