Looks like there are a few RISC OS fans here. What is the best feature of RISC OS that is missing from Mac OS X? For me, it would be a toss up between: * The Save box - drag and drop the file icon to a Finder window to save * Window focus model - the window environment remembers where the (text) input focus was before it was moved. When you close a window or dialog with input focus, the window environment returns the input focus to the last window or dialog that previously had the focus and is still open. IIRC, the window with input focus isn't necessarily the front-most window and clicking on the titlebar doesn't change the input focus - only clicking inside the window pane itself does.
