Cutting as many cords as you can from your life, obviously one of the things you need to detach from the "main unit" is your mouse, so getting your hands on a wireless mouse has to be one of the first steps in the process. (And it's certainly a process.) That's why Canon's new wireless mouse has to sit on your radar. You don't want to have to deal with that regular numbpad, do you? No, of course not. So why not combine your wireless mouse and number keys? Genius, right?
