I’m using mine as a frontend for a simple HTML5 online game, left unattended at a conference so that anybody can walk up and start playing. Any entry-level hackery can be fixed by rebooting, any more advanced abuse can be fixed by flashing a fresh SD card; if somebody physically smashes or steals it, I won’t go bankrupt replacing it.
