Starting with the icon (ahem) that is the Apple Mouse. M0100 was the first Macintosh Mouse which shipped with the original Macintosh back in 1984. The Macintosh Mouse was actually just a modified version of the Lisa Mouse and they are interchangeable.
The mouse is a pleasing block shape. I'm not sure how good this would be to use all day but it seems to be nice to hold. The single (of course) mouse button has a nice click to it even after all these years.
The Macintosh Mouse (like the Lisa one) uses a DE-9 connector. Then quite a standard connector for peripherals.

Well the Apple Macintosh changed the world, or at least showed a different way in computing though it was a number of years before people were clicking icons instead of typing in commands on their personal computers. Without the Mac it may well have happened anyway but it is likely that Apple's stimulus bought about the mouse driven computer world just that little bit sooner.
