[quote name='shrike4242']Trackballs have one big benefit.
If you have carpal tunnel syndrome, it helps reduce the strain on your wrist that a mouse can cause.
All the work on the pointer is done with your fingers, so there's less back-and-forth work to be done on your wrist.
I've been using trackballs for any PC non-gaming activity for about twelve years now and prefer them for something non-gaming. Gaming, mouse is always best.[/QUOTE]
Yeah I use a trackball all day (work), and a mouse all night (gaming). I like not getting pain.
