"While BYOD is a visible benefit for end users. "
I disagree with you there, it is a benefit for a subset of end users. You have made a sweeping statement that is certainly not true in all or many situations. Not all end users want to manage their own device, not all can afford their own device - even with tax concessions, not all need or want mobility. Some end users need high power workstations that due to bulk are not mobile and inappropriate to be anywhere but a fixed location. Some applications for example are not suitable for virtualisation or cloud computing. I think that if you had identified the scope of your statement I would not be so upset by it.
"Hardware support goes from full service.....directions to the nearest major retailers and repair shops."
I am astounded that you can even say this. An employee, on company time, taking time off to get their BYOD repaired or fixed is an astonishing waste of resources. Take out an executive for 2 hours and calculate the cost of that! Consider the scenario, typical of many repair centres, where your device dissapears into the service department for several days. Your employee is either non productive or relying on borrowed equipment, probably from IT. Sending someone off to fix their own device, it simply does not work in many cases. I would suggest that even if repairs were carried out in non business hours, not many employees would want to "waste" their personal time.
I have seen situations where BYOD works very well, but these are currently the exception not the norm.
I agree with a number of the other comments above, I "+"ed a couple of them.
