Microsoft IntelliMouse Optical (IMO) is a family of optical mice in the Microsoft IntelliMouse series.

Notes[edit | edit source]

Sold in both black and white, the white variety is availably singly, while the less common black variety can only be bought in packs. Version 1.0 used an older sensor; black 1.0 mice come in packs of three, while the black revised 1.1 version with newer sensor is sold in packs of five.
The IMO is unusual in being an ambidextrous five-button mouse, with buttons four and five placed on either side; five-button mice (including the Microsoft IntelliMouse Explorer) typically have both buttons 4 and 5 on the left-hand side under the thumb, in a configuration designed for right-handed people. The later Microsoft Comfort Mouse 4500 follows this same design.
