Lucas123 writes: One radical change the consumerization of IT trend is expected to spawn is that by 2017, half of all employers will require workers to supply their own devices for work purposes, 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.
