I am a new Mac user and have Mac OS X version 10.3.9. I would like recommndations and/or suggestions on which mouse to get for my computer. I currently have a Logitech "pilot wheel" which skips and is not very precise. Would an optical or laser mouse be more satisfactory? Would either/both be compatible with my computer? If so, which would be preferable? I would also like your comments on a wireless keyboard and any recommendations. Thank you.
