When I worked, introduced smartphones to be used for job logging by our 50+ strong maintenance force. Started off with Airo A25s as they are extremely rugged but a bit naff. None of the sabotage that I thought might happen - they liked using the devices instead of manually filling in dockets. On that basis replaced them with HTC HD2s and housed these in Otter Box cases which seemed to protect them extremely well. I am informed that, 4 years after they were rolled out they are still surviving.
