For a given task, you may find yourself exclusively using touch as the method of input; in other circumstances you may find yourself using only the keyboard and pointing device; and sometimes you may choose a combination of both input methods.

When using touch as the exclusive method of input for an extended period, you may want to place the monitor in front of the other input devices.
