Excerpt: trackball, I jumped at the chance. Eons ago, back in the mid to late 80’s, I owned and loved one of the earliest Kensington ADB trackballs. It finally was put out to pasture when Apple discontinued the Apple Desktop Bus, but I got my money’s worth from a great accessory.
Excerpt: The SlimBlade Trackball mouse is two mice in one. At first glance it’s a laser mouse and behaves exactly like one. You pair it to your computer (it’s Bluetooth) and then use the scroll ball on the mouse for scrolling up and down and side to side. If scrolling isn’t your thing, a double-click on the Mode Switch turns your mouse into a trackball for computing in hard-to-scroll places.
