Ergonomics is probably the wrong word to use but the magic mouse isn't a comfortable shape for most people. Less subjectively though it's sensor and tracking are terrible compared to modern sensors. All of this can be ignored for most typical work uses I suppose but what can't be ignored is the insanity of placing the charging port on the bottom of the mouse so you cant use it while charging.
