I'm thinking of buying the Mx900 for my iBook, the only question I have is whether you could use the Logitech Control Center software for the Mx700 in order to remap the buttons on the Mx900. It's basically the same mouse isn't it? Has anyone tried that? I would like to be able to get this one rather than the Mx500 with a cable. And no I don't want the Mx700, because I don't want to bother with the transmitter. Thanks in advance.
