At first glance, the Macally Turtle appears to be simply an attractive wireless mouse—perhaps a bit small and light (at 2.5 ounces) for desktop use, but a good size for a welcome traveling companion for your laptop. Examine its belly, however, and you'll learn its secret: inside a flip-open compartment is a USB plug and ribbon cable on a spring-loaded reel. At 30 inches, the cable is plenty long enough to reach left-side laptop ports if you’re a right-handed mouser.
