Patently Apple has discovered a big change Apple is planning for the iPad operating system. Current Apple desktops have a feature called Spaces, which allows users to have multiple virtual desktops on one screen. Moving between screens quickly requires keystrokes and running programs can be organized on each screen for better productivity.
Apple is working on a version of Spaces for the iPad, with a touch interface that would allow for moving between screens. This would increase the screen area on the iPad and make it easy to organize running apps. Windows can be moved from one virtual screen to another by dragging them to the edge of the screen.
