My Wheel Mouse Optical finally got worn out a few months back, so lacking any other wheel mouse, I dug out my old PS/2 IntelliMouse (from 1999), and repaired it. The problem was merely a damaged cable.

However, I would prefer to get a more modern mouse.

I just looked at Microsoft's website, and all I could say was WTF?
