Wacom's Penabled? technology gives you the natural feel and superior performance of Wacom's patented cordless and battery-free tablet technology. You'll find that using an Intuos pen, mouse, and tablet gives you more control, comfort, and productivity. Alternating between the comfortable Grip Pen and the ergonomic five-button Intuos3 mouse reduces repetitive motion. It's an easy and natural way to work. It's easy to use a pen tablet because every point on the tablet has a matching point on the screen. When you move your pen over the tablet the cursor moves in precisely the same way on the screen. Where you touch your pen tip to the tablet is where you click.
