• I had a Microsoft thumb trackball growing up and it was so good. There’s a Logitech with a similar design, but it doesn’t have the same feel. At work, I’ve been using a Kensington Expert and loving it. I don’t know how people use regular mice.

      • I have the Elecom DEFT Pro, which is a finger trackball, but Elecom make thumb trackballs too. I’d never heard of them before I started looking at the current state of the trackball market and took a risk, but have been happy. And they make a left-handed one, believe it or not.
