If you are in one of those groups, a trackball could make sense for day-to-day computing to keep repetitive strain injury in check, but it isn't suitable for high-performance tasks.

If you aren't a gamer or making digital art, your speed and accuracy will improve over time to the point where the trackball becomes second nature. The need to be accurate at high speed is rare unless you play video games or edit art professionally. It's easy to roll the trackball accurately over short distances and to make fine adjustments, but long rolls-like what you'd use to travel across a dual-monitor setup, for example-are generally imprecise and require corrective motions that require more deliberate thought than a standard mouse. Like other ergonomic-mouse form factors-specifically, vertical mice-using a trackball requires you to make a compromise: speed and accuracy in exchange for comfort. Truly, the ring feels like a feature that every trackball designer should steal gong forward, and it's shocking that other devices handle scrolling in other ways.īut let's talk a bit about the limitations of trackballs. The scroll ring, in particular, feels incredibly natural to use: You can easily scroll up and down using one finger without moving the others out of rolling position.

Though it's a four-button setup, with less functionality than most basic mice, each input feels like it's in the right place. Compared to other ergonomic mice and keyboards, that's nothing. It takes just a few minutes to get used to the setup, even for a new trackball user.
