I have a Logitech Mouseman Sensa 3-button serial mouse that I bought in spring, 1995, that still works perfectly. It has a lovely fake burled walnut finish. I've only had to take it apart and clean it twice in the past nine years, in my dust and cat hair filled environment. It's my oldest piece of computer hardware that's been in continuous use.
I hope their new stuff is still built to that level of quality.
This picture was taken sometime in mid 1995, and the mouse is visible. That's the beta version of Windows 95 on the screen, which means I took it some time between February and August.
