Logitech Cordless Optical TrackMan<p>I have no idea why they made it wireless, it ate batteries like crazy, but its still the best trackball I&#x27;ve ever owned.<p>Having the ball at your middle and ring finger gave better control than the thumb driven ones.<p>You can still get it on places like amazon, but at a ridiculous price, 10-20 times what it originally retailed for.
