Hello all. A newbie here and none to computer savvy. I have an imac that I purchased in June of 2007 and I am soon going to replace it with a new one. I read online somewhere that I will need a F 440-800 or a F800 cable/adapter to transfer files and bookmarks. By the age of my mac can anyone tell me which one I should buy and do I need to get this from Apple or can I get one from a big box or local store. Thank you, Therbs.
