Just a couple of questions regarding the Magic Mouse. Got one for Christmas, since I needed a mouse for when am doing Photoshop work. I haven't used it too much, and haven't done any work in Photoshop yet, but am wondering whether I'd need to get a 'Magic Mouse Fix' for extended periods of using the mouse? I've heard that the design of the mouse can cause hand/wrist pain? Secondly, when I use my normal mouse, I often lift it up off my desk, move it, and place it back down on the desk, when am running out of space. I again was told that I shouldn't do this as it can mess up the batteries positioning? ... is that true? Or can I just use it like I would use any other mouse?
