    A large trackball like the Kensington Expert can both move quickly across multiple 4K monitors and precisely point to a specific location.

    By holding down a button, the trackball can also double as a scrollwheel.

    The ergonomics don’t matter to me a lot because I don’t use it a lot. But I love the fast and precise movement.

    As the trackball gets smaller, you have to choose between fast OR precise. Some smaller trackballs deal with that by having a toggle button so you can switch between fast or precise movements on the fly.
