Hi all... I am one who is thinking of purchasing an old refurb model. I am not exactly sure what I am going to get yet though. I have been checking out the refurb store and notice price differences on the same specs and models of imacs. The only differences I can see in them are some say they come with iLife 08 and others iLife 09. I can't see why this would make a $150-200 price difference though. I mean, can't you just update to 09 for $9.95 anyway? So.. I am wondering if I am missing something? i have never purchased from apple before (well not a computer) so I just want to be sure I make an informed decision. The obvious choice would be to go for the cheapest of the model I choose, but I won't do that if there is going to be a major difference in the iMac itself. Help!!??!
