What is a primary benefit of using a touchpad?

A primary benefit of using a touchpad is that it eliminates the need for an external mouse. Touchpads are integrated into laptops and many portable devices, allowing users to control the cursor directly from the keyboard area without requiring additional peripherals. This can be particularly useful when space is limited or when the user desires a more streamlined, portable computing experience. By having the touchpad built-in, it also reduces clutter and the need for managing multiple devices, making it a convenient option for users on the go.

Other options have merits, but the central benefit of a touchpad lies in its ability to function independently of an external mouse, simplifying user interaction with the device.
