Since I am moving my old iMac to the upstairs office one thing I want to do is be able to surf/etc while using my elliptical. I can do the majority of my surfing with a mouse, moving it to select new links etc as needed. However the elliptical is about five feet from the Mac (its a 24" iMac so the screen is very readable). Will the magic mouse work from afar? I haven't tried it yet but I assume the Magic Mouse will work with my old iMac (2.16 C2D gen). If not the MM, what mouse?
