Earlier quoted context omitted.
The Apple mouse's charging port is on the underside, so you can't use the mouse at all while charging.
Thank you for explaining the issue. I guess there are Apple fans (including the author of the article) who can't conceive of a world where there are people who have never used an Apple mouse.
The people who complain about it are almost exclusively people who don't actually use it, but love to complain about it.
