Laptop Trackballs?

What are they for? What do I stipulation to know about them..? Can anybody please explain? thanx :)


Answer:

What a trackball is, is a stationary mouse, and instead of moving the complete thing around the desk, it allows you to of late spin the ball within the mouse. The benefit of this versus a standard mouse with your laptop, is that since you dont enjoy to move it all around the desk to move the cursor, you can a moment ago use the trackball and dont need any room.
it's freshly another way to move the cursor around on the peak, like a mouse or a touch wipe.
its just a mouse alternative .. it would lend a hand in gaming for sure ... i would fairly have an external trackball usb mouse myself tho ...
