Whether it’s a desktop or laptop, I need a mouse. Over time I’ve gradually updated from wired with a ball, to wireless with a laser (?). At work though, I still have the classic Microsoft wired mouse. It works flawlessly and I have no need or desire to give it up. Every once in a while I’ll take a pin and clean out the fuzz. Also, I’ll roughen the spot where my thumb rests by making crosshatch marks. When it’s too smooth, I get an odd touch sensation. As long as there’s texture, I’m fine.
The mouse in the picture has been well used by me and my family. At one point some sort of gel oozed out of the thumb side and I thought the mouse’s demise was imminent. However, after I dabbed up the goo and removed the loose rubber, all was well.
