“For years we have seen statistics telling us the size of people’s screens. We know that 1024×768 is the dominant screen size, and that large resolution screens are coming strong. But, this is useless information. We do not want to know the size of a person’s screen. We want to know the size of the browser’s content area. A person might not use the browser maximized, and other elements — taskbar, toolbars and extensions — takes up valuable screen space.”
