This is a very interesting question for me as I am currently investigating the use of personal mobile devices for professional purposes.
Certainly, the global recession has seen many companies re-adjust their budgets, often at the cost of hardware. Similarly, the rise in smartphones, has seen more and more employees using their own devices in the office.
Maybe this deserves it's own topic, but what is the general consensus on personal devices at work?
And another angle: many companies are blocking social network on the company computers, resulting in employees using personal devices to access them. (in many cases there is not a severe security risks, but there have been plenty of high-profile cases where social networking sites have gotten employees, and employers, into difficulty)
Is it wise to be passing on responsibility for content control onto a device that you have no responsibility for?
What happens when the employees leave the company, and take data with them?
Alex, I know you are trying to prevent them getting data files onto the device, which should stop large migrations of information, however, it wont prevent manual re-entry of information in smaller portions - in some businesses this is just as dangerous.
