Ok as of right now I have the opportunity to either get a early 2011 13" with the 2.7ghz for about $1040 without tax (open box) or a brand new 13" 2.4ghz for about $1000 without tax. Feel like I should act quick since there is only one of the 2.7's. Is there a warranty with open box? What do you guys think? Oh and I plan to use Garageband alot as well as word, excel, internet etc.
