"The Apple USB Mouse, commonly called \"Hockey puck\" (so called because of its unusual round shape), is a mouse released by Apple Inc. It was included with the iMac G3 in 1998 and included with all successive desktop Macs for the next two years. It was the first commercially released Apple mouse to use the USB connection format and not the Apple Desktop Bus (ADB). It is widely considered one of Apple's worst mistakes."@en . . . . . .
