this is it. This is the ORIGINAL Trackman Marble.
The original Logitech Trackman Marble was a thumb trackball which predates that mouse by so much it didn't even have the super-smooth, metallic-painted design. You have no idea what you're on about, perhaps because you're twelve. The device you linked to came years later, after they had discontinued the original marble and replaced it with the Logitech Trackman Wheel T-BB18. I went through about three of the original Marbles back when I was into a whole lotta FPS gaming, they would just die. The Trackman Wheel, on the other hand, just the microswitches die most of the time. It's a relatively easy job to replace them. I got the last replacements out of a T-BB18 that did just become unresponsive, though.
The "Marble" name made a whole lot more sense with the original device, because the ball was smaller. But don't take my word for it, educate yourself on logitech thumb-operated trackballs and then you can scroll down past the device I'm using now and see the original Trackman Marble. Hooray internet.
