The most immediate are pull-down menus at the top of the screen. They work good on a 9 inch screen, they are awful with 27 inch displays.
Another related change are modal dialog boxes. When you have a 9 inch screen you're fundamentally looking at one document in one app at a time. When you got 2 27's that's not true anymore.
