If you want a wired Magic Mouse, sorry but apple it trying to go as wireless as possible. There done with wires for the keyboard and mouse. Well not the keyboard...yet 😀
Get the Magic Trackpad it blows the Magic Mouse away especially if you have a large screen. You can move more distance faster and without having to mouse across your desk.😀
I have a magi. Mouse and mighty mouse (wired) and I can tell you from experience that the magic mouse is by far the much better option. Plus just be lucky you aren't in Australia where the magic mouse and a wireless kb cost 99 each!
