This is an interesting concept and prediction. Do we call it BYOS (Bring Your Own Software)? Weren’t VoIP, IM, and the related unified communications technologies supposed to do this already?
I think people want to have a tangible phone/tablet/laptop in their hands to tinker with and suspect these devices won’t go away for a long, long time. I also believe that BYOD in its current form is here to stay and people in IT and information security are going to have to step up to the plate, get people on board by focusing on their communication skills, and come to a consensus on how to properly secure the devices and information residing on them.
I do think we’ll come around eventually – maybe in the next 8-10 years…until then, it’ll be heads in sand as usual.
