quick question about Lion, not sure if it was asked before but..can every app become full screen'd? or does the app need to be updated with that feature?
i.e do i need to wait for Microsoft to launch an update for Office for Mac, for Lion's features?
"full screen" is not like windows - it doesn't just blow up the window to fit the screen, it adjusts the UI to take advantage of the fact that it owns the whole screen.
as a result, apps need to be updated - the OS can't possibly know what would be an appropriate use of the full screen.
