Mobile Devices

We are moving more and more to mobile devices, such as Surface Pro's, Android Tablets, etc. to get Tessitura out from behind the glass window and into the crowds. I know many others are also investing a lot into mobile as well. This really isn't a "Tessitura" question, but I'm curious on what tracking software others are installing on your mobile devices to track them in the eventuality of it being stolen.

Suggestions and recommendations are appreciated!
