Traditional IT support is the old way
BYOD requires a new support model. It's not IT's job to support the users' many devices. It is now IT's job to provide secure access to the users' data. The Internet, particularly the Web, is universal across all devices, all platforms, and all vendors. A PDF webpage brought up on a MAC is the same that's brought up on a PC. IT just needs to make the PDF available. I mean, apps are moving to web-based anyway. Servers are becoming virtual, anyway. Secure remote network access and business-to-business connectivity are already in use, anyway. IT put all that infrastructure in-place to support our traveling/mobile users and their company-provided laptops. Now, the users want to use their own laptop instead of one bought by the company. OK. So long as company data isn't stolen along with that checked laptop bag at the airport...Oh, that's what was happening before, when they did load that company laptop up with company data, and was then irresponsible with the hardware. Let's see how careless users are with their own $700 iPad.
I wonder how pizza delivery companies do it? Would consumers be willing to pay more for pizza if drivers had fleet vehicles, like FedEx? Or would FedEx charge less if their drivers drove their own cars?
