Yesterday we wrote about the Gamepad Computer Mouse from Evergreen, and now it turns out the same company also has travel-friendly trackball.

The 5-button Evergreen Traveler 350 USB trackball measures 6.5 x 7.5 x 2.2 cm, weighs 77 g, and is compatible with Windows Vista, XP and 2000. The included mounting device lets you attach the trackball to a desk.

Just as with the other mouse, this one also happens to be out of stock. The Traveler 350 is otherwise sold by Donya for 2,999 YEN (about $28 USD).
