I know that this link has been posted in another thread somewhere, but I can't seem to find it. Anyway, questions I have are about the processors.. I know that this is a 2010 model. My wife bought this exact model new then... My question is about the 2.13 core 2 duo vs. the 1.6/1.8 i series. What are the major differences? Speed? Battery life? Thanks for helping me figure it out. http://www.macmall.com/n/macNavLinks-304?q=8836730 Part of me wants to wait for the ivy bridge update.. I don't know why or how it will make it better, but i want it. lol. No tax, no shipping, with 3 year apple care is 1350net.
