I just purchased an imac 27" 3.4 ssd as my main photo editing machine. I currently own an Santa Rosa Macbook pro and a Unibody Core 2 Duo Macbook pro that I am hoping to sell to help fund this purchase. But I think I need another laptop. I'm having trouble deciding between a 13" air and a 13" macbook pro. Both clock in higher then my current machine so I am confident I could use either for weekend editing when I travel for work for a few days at a time during the week. To be honest I'd rather have the air with the higher res screen and awesome form factor but I am wondering if I will prefer the performance of the macbook pro for when I need to spend a day or two editing away from home. The screen itself is not the biggest issue as I have a 24" led display to connect either laptop too. Price is a concern too. I'd love to hear others thoughts. Thanks.
