I'm looking into buying a new MacBook Pro and am undecided between the 13 and 15 inch model. I'm thinking of getting the top of the line 13" with upgraded 2.8 i7, but I only see a 15" equivalent with a 2.6? This doesn't make sense to me why this isn't an option on the 15". I'd like the bigger screen but will also be using it with a Cinema Display, so I'd prefer the better processor. Wondering what everyone's thoughts on this are as I haven't seen any threads discussing it.
