(For example, a few 'travel gaming' mice exist.) Let's take a look at the gaming field first, then move on to other genres and aspects that affect all mice. There's a lot of variance within each, and some crossover among all of these classes. Generally speaking, travel mice are wireless and battery-powered, so you may want to bring along a spare set of AA or AAA batteries if that is what they use.īeyond these 'ordinary' mice are two key mouse genres: the gaming mouse, and the ergonomic mouse. For this same reason, however, travel mice tend to be small for most hands-you can use them just fine for short stints, but they become uncomfortable over long periods due to the unnatural grip required. They're designed to fit easily into the pocket of a backpack or laptop bag. Travel mice (or 'mobile mice') offer many of these same features but come in a smaller size.
