Staff Time
The device sounds neat. But it also highlights the problems with opening operations up to policies like BYOD. It is Human nature for some people to keep pushing the envelope and trying to shoehorn in different or weird things. It inevitably ends up being a huge pain in the ass for everyone and makes for hurt feelings and disgruntled staff.
Personally I'd rather my IT guys stay focused on business operations instead of vetting new gear all the time and redesigning policies to accommodate exceptions. Maybe I'm overly pessimistic about it, but it all seems like a big expensive hassle to me.
