I’ve never cared for trackball mice (to put it mildly), but I can understand their advantages: they offer high precision in a small space with little or no hand movement necessary. In other words, they’re perfect for traveling, since you can practically use them in your pocket. It’s kinda funny, then, that most trackball mice are giant sculptural behemoths, not fit to be taken anywhere, by anyone, at any time. The Genius Traveler 350 is a tiny little USB optical trackball with a retracting cord, integrated hotkeys, and a scroll wheel. It measures about 23cm x 13cm x 7cm, and looks to be about $30. It’s so practical I’d get one, except then I might be seen in public using a trackball, and we certainly can’t have that, can we?
