I'm going from memory. This was before the World Wide Web, when we still used dialup and serial cables, in the early days of the Apple LaserWriter when Aldus PageMaker ruled the world.

If I recall, the mouse had a high resolution and extra buttons for things like copy and paste. Something about an ergonomic design comes to mind, but I'm not sure about that.

I think that Byte! Magazine featured a review, but again, I'm going from memory here, this is in the late 1980's when Desktop Publishing was the future of computing!
