Pen
An important difference between traditional PCs and tablet PCs is that you frequently use a
pen instead of a mouse and keyboard to interact with the computer. The pen includes a
pressure-sensitive tip, a function button, and an eraser. The pen contains no batteries and
requires no external power.
For information about using the pen, see “Using the pen” on page 21.
