The Microsoft IntelliMouse was so good. This was something I realized at the time and hoarded them. I now have a wonderful stash of that mouse.
Their joystick offerings (Sidewinder) were top-notch, for example.
Before MS gutted the PC gaming hardware division to focus on forcing the Xbox on us..
Maybe there would be a demand for a website that lists where you can buy obsoleted programmer gear like the IntelliMouse and Thinkpads.
