Even if you're not crazy about soccer, the World Cup USB Twin has a split personality that's just downright useful, converting from a tiny road-warrior mouse to a desktop-sized unit in a snap. Just fit the World Cup-themed cover over the mini-mouse, and it's good to go in its full size. The $22 mouse has an 800dpi optical sensor and a luminous blue scroll wheel, along with a retractable USB cable that keeps things tidy in your overnight bag.
Since we're Americans and don't really care much for an unbelievably boring sport that assumes that arms are a marginally useful part of the human body, we're thinking this product would be a lot more desirable if it offered variety of themed covers; anything but soccer.
