Hi,
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 ??
