[Wang, Quanxian] If you want to use multiple users, there is definitely fine.
But to design multiple display, and multiple seat, I don't think you really
need bind them together with multiple user mechanism.
It is only limit your resource to designed model. It is not flexible.
By the way, I have two kids. More friends. I respect their privacy. I am only
doubt binding mechanism. Don't limit everything into multi-user. *** They
should be the apps limit or share instead of multi-user.***
