We've had the same challenge with some of the hi-end users. One thing you can do is emphasize the enormous costs of data loss, particularly if you are in Health care or Finance. If, say a DBA sends themself a spreadsheet with say, 10000 customer social security or credit card numbers, and the data is lost, at least in our State their is a reporting obligation, and an obligation to pay a 1 year credit reporting fee at $100 a pop...In our state if the device is encrypted, there is no reporting obligation, but I know from personal experie nce, there is enormouse peace of mind if you lose your device and know that no one can get into it. Probably all it will take is for one device to be lost, with data, and all of the senior execs will change their tune. Good Luck.
