(Six displays, side by side, from a page describing the graphics features of the new Mac Pro.) We’re going to need some new OS concepts and interaction techniques to deal with really big screens. It really won’t do to have to mouse over six displays to get to the File menu (note how the picture shows an image, not screens of applications)—or hit the “Start” button. Menu bars will need to be attached to applications; Docks, menu extras, system trays (i.e. anything in a fixed position on the screen) will need to go. Display-crossing mouse movements will be done via Spaces? Or touch-to-move? Who is researching this?
