The purchase price of the device (investment/capital expenditure) is not neccessarily the greatest expense. Sure, in many smaller companies it will be, but in companies that have (for example) information protection policies or systems/services beyond email, support and operating costs for BYOD can in fact be more expensive. Consider the simple scenario of using GMail, calendar and contacts - on a MacBook you need to know to configure it as an Exchange service, or you only end up with mail. Many may want to enforce some sort of policy on the device - such as requiring a PIN to unlock. Spread that across all the device types users might bring in and compare that with managing just a single device, for example BlackBerry. Sure, there are tools these days that make it easier to manage. Windows 8 and Windows Phone 8, for example, can be managed using SCCM. But in many cases BYOD does't deliver the (often naive) expectations of savings.
