I think it would be nice to have a wired USB mouse which uses a regular detachable USB cable like a Mini USB cable or Micro USB Cable to connect the mouse to the computer.
If the mouse breaks, the user still have a Micro USB cable, and can buy another working mouse to connect it to the cable. Sometimes finding the correct USB cable to unplug on a back of a PC with many USB devices can take a long time, so just replacing the mouse can be easier instead of also needing to unplug the cable with the mouse.
If the cable breaks, the user can just replace the cable.
