The main advantage of touchpads is that their compact size allows them conveniently fit below laptop keyboards. However, their small size may affect the pointing accuracy; even tiny movements on the touchpad can cause the mouse pointer to make a large movement.
It may take completely novice computer users a while to master the use of a touch pad. The sensitivity of the touchpad can be adjusted to aid in correcting scrolling speed issues.
The lack of moving parts on a touch pad means that it is easier to maintain and less likely to collect dust and dirt. Since the touch pad utilizes sensors to collect movement data; sweaty or moist fingers can cause signal disruption.
