Produced by Doa Korea, the Slim G4 may be one of the smallest mice ever devised. It is only 0.2 inches thick, and when extended, 3.7 inches long -- but it is able to collapse to half that length for travel, and stores inside a laptop's PC Card slot. Moreover, a spool underneath the mouse allows users to store the USB cable without taking up more space. Inside the mouse is an optical sensor; controls include two buttons and a touchpad in place of a scrollwheel. Four colors to choose from include blue, pink, ivory and silver. No pricing is immediately available. [via Akihabara News]
