The Slim G4 mouse definitely doesn't look like your regular desktop mouse, and is certainly far from reality when it comes to the world of notebook mice. Produced by Doa Korea, the G4 measures a mere 0.2" thick and 3.7" long when extended. When you need to pack it up for travel, just collapse it into half its length and slot it inside your laptop's PC Card slot. A spool located just below the G4 stores the USB cable without taking up additional space. Pricing details are currently unavailable, but you can choose from blue, pink, ivory, and silver colors.
