Shift to commodity hardware
BYOD has more or less arrived: people are bringing their own hardware into the work environment and using it for some stuff. Networks have largely been updated to provide internet capability whilst insulating infrastructure.
However, the major shift is from PCs to managed consumer devices. As the article points out: if you don't own it, you can't control it. Devices that provide strict separation between business and private environments are needed so that the PC can die and be buried in peace and if someone breaks or loses their device they can be up and running with a new one as quickly as possible. Whether someone has a company device which has some space for them to do their own thing is, of course, important. But the trend is definitely taking some kind of universal device with you and popping it on some kind of dock and doing stuff.
But the problem is the age old: device versus network?
