That problem for businesses started with giving employees access to the internet. It has nothing to do with Unity and everything to do with management ignorance of computers. When I was at work I was often prevented from using a computer for work purposes because a manager was searching the company web site for another job.it detracts from productivity and gives employees access to gimmicks that rob the productivity of ligitimate office time.
I do not support this partition. This is just another anti-unity attempt to insult Ubuntu and its developers.
