History of Kensington Expert Mouse

Kensington was famous, throughout the 1990s in the Macintosh community, for its large ball trackball. In almost all 1990s, the Kensington trackball is the coveted device for high-end Mac owners for all their graphics design needs.

Since the 2000s or perhaps late 1990s, their market got eaten by Logitech Trackballs, and i think their product's quality and innovation also gradually declined.

I think one major problem is that the ball has a lot friction. I remember i tried it in stores and think the friction is the worst of all trackballs i've put my hands on.

Also, Kensington's classic design always seems unwieldy for me. That you have to bend your wrist up to use it. If i actually use this, i'll have to put a folded-towel in front to rest wrist on.

This trackball is notorious for not supporting Windows 7. ( update: Shadow Skill says Windows 7 driver has been released.)
