Multi-monitor support, especially 3 monitors would be awesome.
Imagine stitting in front of the:
left-of-front, front, and right-of-front views.
Switch to the back and see the:
left-of-back, back, and right-of-back view.
Look up and see:
left-up, up, and right-up.
Periperal vision would take on new meaning. Anyhow, it'd do 'till we get a holodeck.
