People who do precision graphics work have long known that a trackball can provide much finer control than the familiar mouse. But trackballs, which look like oversize, upside-down mice, have been uncomfortable to use. Now, there's the sleek Orbit from Kensington Microware (800 535-4242), which is easy on your hand and wrist. The PC version retails for about $55; a Mac model, a few bucks more. Both feature a translucent electric-blue ball, about two inches wide, that pops out easily for cleaning. If you sometimes find it tough to move the cursor just where you want it with a mouse, the Orbit could be for you.
