I've been thinking about the same thing. The window manager needs to be built into the OS, really. I think we'll see something built into Android for this soon -(standard 2d app surfaces in a 3D360 VR environment). I'm not sure the current display tech is that good for your eyes/brain to be staring at it 8 hours a day, never mind the current screen resolution. But eventually it will be, and using something like this will enable you to work anywhere without having to carry large screens with you.
