Hi, I am looking at this very moment at the Apple online store at a MBP 13" and a MBP 15" Putting similitudes aside, the main difference I see is in the processor. The 15" has a 2.4GHz Intel Core i5, and the 13" has a 2.66GHz Intel Core 2 Duo. What is the advantage of having the "i" processors over the Core 2 Duo, and for what applications are they meant? Is it likely that the 13" MBP may have an "i" processor for the next update ?? Thank you very much, very kind regards, igmolinav.
