If I were to ask you to name Microsoft's most famous and longest running product

, you would almost certainly say "Windows".

But another product of the company has been in the market for an even longer time.

Microsoft started selling its first computer mouse in 1983

A year or two ago Macintosh and other computers made pointing devices standard-issue

And two years ago the first version of Windows was released.

The Microsoft Natural Keyboard followed in 1994. Since then, the company has offered a range of Microsoft-branded PC accessories,

ranging from successful ones like the Microsoft Ergonomic Keyboard to short-lived experiments like the Microsoft SideWinder gamepad and joystick.

Mice and keyboards made by Microsoft aren't going away
