Hi there. I'm planning on purchasing my first Apple computer (an iMac.) Do you folks think getting a wireless keyboard and mouse from the apple store rather than the mighty mouse would be worth it? I'm not concerned about the extra money, but functionality wise. It'd be nice to have an absolutely clutter free workspace where i could just put my mouse and keyboard away if I so desired. However, are they responsive and accurate enough to do Photoshop work with? How long do the batteries generally last? Thanks guys!
