I was installing some stuff on machines this week. One person had that tracker ball mouse. It was horrific. Took me forever to navigate with that thing.
I haven't used a mouse or a track ball for years. But if I did, it would be the one on the right.
I'm not sure what those are, wink.
Never mind. 😜
My thumb dislikes thumb trackballs. It gets all crampy just looking at it!
I've never even seen one before now. I'd probably put a heating pad on it to reduce the swelling... :^D
Silly Tlaney...you have two thumbs on your own hands.
