Lucas123 writes "Half of all employers will require workers to supply their own mobile devices for work purposes by 2017, according to a new Gartner study. Enterprises that offer only corporately-owned smartphones or stipends to buy your own will soon become the exception to the rule in the next few years. As enterprise BYOD programs proliferate, 38% of companies expect to stop providing devices to workers by 2016 and let them use their own, according to a global survey of CIOs by Gartner. At the same time, security remains the top BYOD concern. 'What happens if you buy a device for an employee and they leave the job a month later? How are you going to settle up? Better to keep it simple. The employee owns the device, and the company helps to cover usage costs,' said David Willis, a distinguished analyst at Gartner."
