1. Trackballs

Ergonomic experts have been telling us for years to use a trackball. Your hand rests in a more comfortable position, and your wrist moves less frequently. And yet, I'm pretty sure no ergonomics expert has ever used one. If they did, they'd know that as you move the larger cue ball on the top, the mouse can jump erratically. Worse, a trackball is less precise for clicking on Web links—a common task for anyone at work these days.
