Yes. It is not a stand-alone product. Think of it as a replacement for a mouse. It's useful because it's much easier to draw smooth lines with a tablet than with a mouse, and also because it adds features that no mouse has. By varying the hardness with which you press on the tablet, you can go from a very fine line to a bolder one without having to stop to make adjustments. You can also use the pressure you apply to the tablet to adjust how transparent what you draw or paint will be.
